Trump admin live updates: Trump says Musk will 'pay the consequences' if he funds Democrats

As Elon Musk continued to slam the president on X, President Donald Trump took to his own social media platform to respond.

Trump claimed in a Truth Social post Thursday afternoon that Musk was "wearing thin" and he asked the billionaire to leave.

"I took away his EV Mandate that forced everyone to buy Electric Cars that nobody else wanted (that he knew for months I was going to do!), and he just went CRAZY!" Trump posted.

The president wrote in a follow-up post, "The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon's Governmental Subsidies and Contracts. I was always surprised that Biden didn't do it!"

Elon Musk and President Donald Trump have not spoken as of Thursday morning, according to two sources familiar with the president's conversations.

Multiple administration officials have attempted to reach out to Musk and his representatives personally amid his criticisms of the spending bill, but their calls and texts have not been returned, several sources told ABC News.

Earlier this week, Speaker Mike Johnson said he tried to call Musk and was waiting for a callback. Johnson said the two planned to connect Thursday.

Before speaking out publicly against the bill, Musk personally pushed some lawmakers, including Johnson, to keep the tax credits for electric vehicles in the bill, according to two people familiar with conversations.

As of now, the Tesla that Trump bought to show support for Musk is still on the White House complex, according to two sources. It remains unclear if it will stay there.

The White House declined to comment. A representative for Musk has not immediately returned ABC News's request for comment.

President Donald Trump brought up the alleged autopen use by former President Joe Biden and made more allegations without any evidence.

"I know some of the people that used that autopen and those are not the people that had the same ideology as Joe Biden. These were radical left lunatics that use that and they didn't get elected," Trump alleged before making a false claim that Biden didn't win the 2020 election.

President Donald Trump was asked again on Thursday when he will make a decision regarding sanctions on Russia, which he's threatened repeatedly over the past several weeks.

"It's in my brain, the deadline," Trump said. "When I see the moment where it's not gonna stop ... we'll be very, very tough. And it could be on both countries, to be honest. It takes two to tango."

Trump also discussed his phone call on Wednesday with Russian President Vladimir Putin, saying he compared the Russia-Ukraine war to two boys who hate each other "fighting in a park" and whether it is best to break them up or let them fight.
