President Donald Trump threatened Thursday morning to break off an upcoming meeting with Mexican President Enrique Peña Nieto after Peña Nieto reiterated that his nation would not pay for Trump's border wall.

"Mexico doesn't believe in walls," Peña Nieto said Wednesday. Hours later, Trump tweeted:

"If I'm not mistaken, this is straight from the 'you can't break up with me [because] I was already breaking up with YOU' manual of [international] diplomacy," The Washington Post's Rebecca Sinderbrand quipped.

House Speaker Paul Ryan told MSNBC on Wednesday night that "there are a lot of different ways of getting Mexico to contribute to doing this, and there are different ways to defining how exactly they pay for it," but at first, "we're going to pay for it and front the money up." When interviewer Greta Van Susteren said the estimated price tag is $8 billion to $14 billion, Ryan agreed, saying, "That's about right." Other estimates put the price as high as $25 billion for just construction. Jeva Lange

President Trump on Monday evening expressed his displeasure with Nevada state lawmakers voting to automatically send mail-in ballots to all voters, telling reporters he will sue to block the bill.

The legislation was approved on Sunday, and Gov. Stephen Sisolak (D) signed the measure into law on Monday evening. Trump, who in April said mail-in voting "doesn't work out well for Republicans," claimed on Twitter Monday morning that the lawmakers conducted an "illegal late night coup" and the "Post Office could never handle the Traffic of Mail-In Votes without preparation. Using Covid to steal the state. See you in Court!"

During a press conference later in the day, Trump repeated his assertion that the U.S. Post Office does not have the infrastructure necessary to handle an influx of mail-in ballots, and said he plans on having the lawsuit blocking Nevada filed on Tuesday. Trump was asked whether he would issue an executive order on mail-in voting, and responded, "I have the right to do it. We haven't gotten there yet. We'll see what happens."

Several state election officials have said they will expand mail-in voting to keep voters safe during the coronavirus pandemic. Experts say voter fraud is rare, especially when there are proper safety measures in place, and a study released earlier this year found that universal vote-by-mail does not benefit any political party.

The Apple fire in Riverside County, California, which has burned more than 26,400 acres and is only five percent contained, was ignited by a malfunctioning diesel vehicle, fire officials announced on Monday.

The California Department of Forestry and Fire Protection said in a statement that on Friday evening, the vehicle released burning carbon from its exhaust system, which sparked the fire in Cherry Valley, an unincorporated town about 75 miles east of Los Angeles. Anyone with any information on the vehicle is asked to contact authorities.

The blaze has spread across hillsides and up the side of Mount San Gorgonio, destroying one home and two outbuildings. Nearly 8,000 people have been evacuated, and so far, no injuries have been reported. There are more than 2,300 firefighters on the scene.

"Much of the fire activity is being driven by the record-low moisture content of the vegetation in the area combined with high temperatures and low relative humidity," fire officials said on Monday afternoon. "These conditions are contributing to active fire behavior both day and night." Catherine Garcia

On Monday, Israeli jets struck several Syrian military targets, including intelligence-collection systems, observation posts, antiaircraft artillery facilities, and command and control centers, the Israeli army announced in a statement.

The army said this was in response to the Israeli military foiling an attack early Sunday, after troops spotted four suspected militants from Syria attempting to drop explosive devices along a security fence in the Golan Heights region; they were fired on by Israeli troops and aircraft and killed.

"The Israel Defense Forces holds the Syrian government responsible for all activities originating from Syrian soil, and will continue operating with determination against any violation of Israeli sovereignty," the army stated.

Last week, Israel said Hezbollah militants attempted to cross into its territory from Lebanon, and Israeli Prime Minister Benjamin Netanyahu said the group's sponsor, Iran, is trying to cause chaos by "entrenching its military in our region." Hezbollah denied being part of the operation. Catherine Garcia

World Health Organization Director-General Tedros Adhanom Ghebreyesus said on Monday he is hopeful that the six coronavirus vaccine candidates now in their third phase of clinical trials will be effective, but warned that there is "no silver bullet at the moment and there might never be."

Until there is an approved vaccine, the world must follow "the basics" of disease control, he said, which involves testing, isolating, tracing, and quarantining, as well as social distancing, regular hand washing, and wearing masks. "The message to people and governments is clear: Do it all," Tedros added.

On Jan. 30, the WHO declared COVID-19 a public health emergency, and at the time "there were fewer than 100 cases and no deaths outside of China," Tedros said. Today, worldwide there are 18.1 million COVID-19 cases, with more than 690,000 people dying of the virus, according to the Johns Hopkins University coronavirus tracker. Catherine Garcia

A Department of Homeland Security intelligence report leaked to The Nation has some experts skeptical of the department's motives.

The report targeted several left-wing American activists whom the department would normally be prohibited from gathering intelligence on unless they had reason to believe the individuals were operating on behalf of a foreign power. The people named in the report, many of whom have identified with far-left causes, do have connections abroad — they traveled to Syria in the past and fought against ISIS alongside Kurdish factions like the YPG, PKK, and the Peshmerga.

The U.S., of course, considers ISIS an enemy, as well, so it may seem surprising that the U.S. government would focus on people who volunteered to fight against the terrorist group, but critics argue the Syria connection could be a front to root out potential antifa members. (Some of the individuals denied membership in antifa, which does not necessarily operate in any organized capacity to begin with.)

The report eventually appears to conclude there is no evidence of a "centralized effort to give marching orders to returning antifa-affiliated" U.S. residents, but either way, the briefing didn't sit well with everyone. "They targeted Americans like they're Al-Qaeda," a former intelligence officer in the department with knowledge of the operations told The Nation. "They were essentially violating people's rights like this was the 60s." Read more at The Nation. Tim O'Donnell

The Philadelphia Phillies and Miami Marlins received some encouraging coronavirus-related news Sunday and are likely return to the field soon, but things aren't going as well for the St. Louis Cardinals.

The Cardinals have had 13 members of their clubhouse — seven players and six staff members — test positive for the coronavirus. The team had its its weekend series against the Milwaukee Brewers postponed, and will no longer travel to Detroit for the next slate of games against the Tigers. That makes them, along with the Marlins, who have had 18 players test positive, and the Phillies, who paused play out of caution but do not appear to have an outbreak, the third team to miss at least a week of baseball games during the young season.

Despite the possibility of cancellation, MLB still isn't planning to pause the season overall, and teams like the Cardinals, Phillies, and Marlins, will seemingly do what they can to make up as many games as possible, even if they don't play a full 60-game season.

While the baseball situation is bleak for St. Louis, the players and staff are — more importantly — in good condition, exhibiting either "light" or no symptoms, general manager John Mozeliak said. Tim O'Donnell
