mandatory e vok wags orders tonight. and there are fast-moving developments in the arson investigation. abc's will carr leading us off, he's on the scene of the cranston fire in mountain center, california. >> reporter: tonight, with nearly 70 large, out of control wildfires burning across the western united states -- >> it's just a massive plume of smoke. >> reporter: -- california's governor declaring that state of emergency for two california counties. the cranston fire exploding in the last 24 hours, forcing thousands to evacuate. this fire has raced down the hillside behind me. it's being fueled by this bone dry brush. and these scorching temperatures. you can hear a tree going up behind me. it is 110 degrees out right now, it's not showing any signs of letting up. the fire roaring through this lumberyard, leaving a hellish snapshot straight out of armageddon. this is one of the most intense feelings of heat that i've ever felt. it's easily burning over 1,000 degrees right here. and at least five homes destroyed so far. 4,700 acres now charred.

the fire 5% contained. >> we were so afraid this was going to happen. >> reporter: authorities say the fire was deliberately set, arresting 32-year-old brandon mcglover overnight. he's now charged with five counts of arson. >> and i'm glad they caught him when he did, because he had intehayliee brooks questioning someone would want to create this trail of destruction. >> why would you do that? why would you put so many people at risk? there are so many homes burned down. >> reporter: the cranston fire now one of six burning in california. the car fire near redding now 20,000 acres. and near yosemite, the ferguson fire charring more than 43,000 acres. parts of that park still closed. firefighters across the region battling fierce flames and scorching heat. >> will carr back on the scene for us live tonight from mountain center. the charred scene right there behind you, will. and you reported there that this was deliberately set. you've learned the almost unbelievable way they caught their suspect? >> reporter: that's right, david. witnesses tell us they saw this

suspect driving across this ut window. they called the police and that led to the arrest. and with these conditions, mother nature really doesn't need any help creating devastation like this. david? >> thinking about all those families tonight. will carr leading us off. will, thank you. we're also learning more tonight about tornadoes touching down here in the northeast, and with force. two ef-1 tornadoes in western massachusetts bringing 1 100-mile-an-hour winds, leaving a path of destruction in upton, massachusetts. powerful flood waters buckling and destroying the asphalt in central pennsylvania. the susquehanna river still under flood warnings after a foot of rain. rob marciano in easton, pennsylvania, with the lehigh river raging behind you. >> reporter: it is rushing violently into the delaware river, which is still rising tonight. thankfully, today was a dry day. but tomorrow, more rain in the forecast and again next week. will's time it. storms are going to fire around 3:00, 4:00 in the flood zone and pushing to the i-95 corridor,

baltimore, philly, d.c. and new york around 8:00, 9:00. some of these could be rough again like they were last night. we have to look out for that. and we have a severe watch out for the high plains and likely there again tomorrow for severe storms. and the heat today peaking in the west, but it only cools by a few degrees tomorrow. advisories and warnings remain up where those wildfires burn hot tonight. david? >> rob marciano, thank you. and the other major headline tonight involves facebook. a disastrous day for the social media giant. the biggest single-day drop for a u.s. company ever, losing nearly $100 billion in just one day. and look at the gra ni the stock holding study for four days there and just look at the drop today, plunging 19 percentp abc's kayna whitworth on what this means. >> reporter: tonight, investors fleeing facebook. the world's largest social media

platform losing close to $100 billion in stock value just today alone. >> you're seeing users spending less time on the platform, that means less advertising revenues, and ultimately, that's not something investors want to see. >> reporter: the losses stemming from a weaker than expected earnings report. and follows a tumultuous period for the company that included the discovery of huge numbers of fake facebook pages linked to russians during the 2016 election. fake ads like this one of a popular cartoon saying "dora the explorer knows how easy it is to cross the border. we need to stop this madness. we need trump." and then word that cambridge analytica, a firm hired by the 2016 trump campaign, may have improperly obtained information from up to 87 million users. all this prompting zuckerberg to go to capitol hill and apologize. >> it was my mistake, and i'm sorry. >> kayna whitworth with us live

tonight. we watched that earlier this year, the data used to target users during the campaign. zuckerberg lost billions himself today, kayna? >> reporter: david, he lost more than $15 billion, but he also says that facebook's lower than expected earnings are due in part to the company reinvesting much of their money in security for the site. this, as their number of users is dropping significantly. david? >> kayna, thank you. we're going to turn now to the president tonight, asking american farmers to be patient, and just today, saying to them, you're not going to be too angry with trump. the president was in iowa today, we have heard from farmers in thatte. we'll hear from farmers in wisconsin tonight, who say they are feeling the effects of this trade war, ignited by the president. they say their bills are already mounting. but the president is hoping for patience from many farmers who he counted on to win. abc's terry moran again tonight. >> reporter: in dubuque county, iowa, president trump came bearing gifts for some of his loil supporters now getting

anxious about his trade agenda. >> i have to say, because we have a lot of farmers in this place, we had this hat made up, the john deere colors, make our farmers great again. >> reporter: and it wasn't just the hats. the president offering about acknowledgement that his trade war with china is clobbering farmers here. >> china wants to attack the farm belt because they know those -- the farmers love me, they voted for me, we won every one of the states. they're not going to win, just so you understand, we have all the cards, we're going to win. >> reporter: the upper midwest, a crucial part of the president's base, but now, he's faltering. look at neighboring wisconsin. just 31% say he should be re-elected. and 63% say he shouldn't. in other mid western states, similar numbers. most farmers in this region supportive still, but worried. like mark recker, who grows sand s and soybeans. >> farmers have been willing to

give the president latitude, but now it's hitting close to home. the reality is here. lower prices. we're going into the fall with a larger crop, it looks like, and we're going to have questions about, how are we -- what are our opportunities for profitability coming from now? >> reporter: the president tweeted famously back in march, "trade wars are good and easy to win." but they're not. so to shorep the farmers, the trump administration has announced a $12 billion bailout, but don't call it a bailout. steve mnuchin hates that word. >> we're not bailing out any farmers. that's a ridiculous comment. that's not a bailout. >> reporter: whatever you call it, farmers aren't happy. >> as farmers, i can tell you, we would rather get our income from the market. it's a handout that we really don't want. >> reporter: today, the president claimed he'd found a fix. trade with europe, part of the agreement he announced in the rose garden yesterday. >> basically, we opened up europe, and that's going to be a great thing for europe and really going to be a great thing for us and it's going to be a really great thing for our farmers. >> reporter: but already today, europeans are backing away from

the idea of imports american agricultural products, especially if they're genetically modified, cost more because of the shipping distances or use chemicals banned in europe. and in wisconsin, where michael slattery farms soybeans, there's fear the trade war will do lasting damage. >> for me, this is a great loss. not just because the price has dropped, but our future markets will be taken away from us. >> reporter: he says farmers are the dupes in this whole process. >> american farmers aring go to be watching this very closely. they're feeling the effects first. terry moran joins us live from the white house again tonight. and terry, president trump says the u.s. will win this trade war, but some of the farmers say the pain could be permanent? >> reporter: that's right, david. the concern is that it's taken years, sometimes decades for american farmers and producers to build the business relationships, earn the market share and now that they're out of that market, competitors from other countries are rushing in to steal all that. the longer this trade war goes on, the risk of longer-term

damage is greater. david? >> terry, thank you again tonight. and there was another major development involving the president today and his company. tonight, the cfo of the trump organization, who has handled the family's finances for decades, has now been subpoenaed in the michael cohen case. here's abc's chief justice correspondent pierre thomas tonight. >> reporter: he is perhaps the most powerful person in the trump organization not named trump. the gee -- company's chief financial officer, allen weisselberg. and tonight, word he has been subpoenaed by federal prosecutors. weisselberg at trump's side for decades, even doing a cameo on "the apprentice." >> replacing george this week is my chief financial officer allen weisselberg. and you think george is tough? wait until you see allen. >> reporter: he currently runs the family's company, along with the president's sons eric and don jr. and he's now caught up in the wide-ranging financial investigation of former trump fixer and personal attorney, michael cohen. prosecutors in new york also

examining whether cohen broke laws trying to quiet women who claimed to have had affairs with trump. weisselberg front and center in a newly released secretcord you trp and cohen apparently discussing a plan to buy the rights to the story of a playboy playmate who says she had a relationship with trump. on the recording, cohen proposes creating a shell company to do the deal. >> and i've spoken to allen weisselberg about how to set the whole thing up with funding. >> so, what do we have to pay for this one, 150? >> yes. >> reporter: prosecutors now using a federal grand jury to question weisselberg, the president's loyal long-time deputy who knows all there is to know about the trump family business. >> all right, so, let's get to pierre thomas, live again tonight from washington. and pierre, we know that prosecutors are listening carefully to that recorded conversation with the president, in which michael cohen actually mentions that cfo, allen weisselberg, in connection with the hush money payment? >> reporter: that's right, david. that tape is of high interest and they just got access to it this week. weisselberg is a key witness and

a gateway to knowing more about the president's finances. trump wrote in one of his books, "allen has been with me for 30 years and he knows how to get things done." david? >> pierre, thank you. our team here has been reporting on the children who were separated from their parents at the border. by midnight tonight, the government was told it has to reunite thousands of children with their parents. so, will they make the deadline and how many children and parents are still waiting? abc's chief national affairs correspondent tom llamas on this again tonight. >> reporter: right now, reunions like this playing out across the country. but still, hundreds of migrant children remain in limbo, despite a court-ordered deline. the government ordered to reunite more than 2,500 children separated from their families. tonight, more than 1,800 children back with their families. more fontmonths, we've reported the children taken from their parents at the border. ramped up under the trump administration's zero tolerance

immigration policy. and we saw up close the trauma families face. this mother, crossing illegally into the u.s. she told me she's been traveling for a month. she broke down. she tells me gangs threatened to kill her child. they already killed his father. and we were there as this little boy wasreited wh s afte l wit a foster family in michigan for elshocked. we've j the delovernmen sing more than 700nre ineligible for ir parents, including hundreds of cases where the parents are no longer even in this country. the government will now have to work and try to figure out how and if they'll be able to get those families back together. david? >> just to be clear, some of the parents were actually sent home already. >> reporter: that's right. they either deported or left on their own, but the government can't find them in some cases. >> tom llamas, you'll stay on this. thank you. to other news tonight, and to a short-lived effort to try

to impeach rod rosenstein, overseeing the mueller investigation. 11 conservative congressmen have now put off a drive to impeach rosenstein, at least for now. just hours before congress left for a five-week break, they introduced articles of impeachment, accusing rosenstein of mishandling the russia investigation. democrats tonight call it a political move on behalf of the president. republican speaker paul ryan says he doesn't support impeachment. the measure would likely fail in a vote. there is still much more ahead on "world news tonight" this thursday. the family speaking out tonight, outrage over the stand your ground law. a fight over a parking space. one of the customers shooting and killing the other, but no charges. the breaking development involving the well-known doctor shot and killed while riding his bike. he once treated president george h.w. bush. what police have now revealed tonight. then, the young state trooper in training killed on an american highway. a fellow officer's weapon was used in the crime. and nearly 17 years after 9/11, what a fall i will hmily

self-defense under florida's stand your ground law, which allows people to use deadly force in order to protect themselves and police agreed. tonight, his family is urging the state attorney to reverse course and charge him, saying the video shows mcglockton turning his body away from drejka after that shove, proving he was not a threat. now, at least 27 states have similar stand your ground laws, and tonight, the family attorney is demanding that that law be changed so that someone who starts a confrontation can then not claim immunity. david? >> linsey, thank you. coming up, the new medical headline about alzheimer's. and new developments tonight in the murder of that well-known doctor who once treated former president george h.w. bush. ornis were made for better things than psoriatic arthritis. as you and your rheumatologist consider treatments, ask if xeljanz xr is right for you. xeljanz xr is a once-daily pill for psoriatic arthritis. taken with methotrexate or similar medicines,
