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

House Speaker Mike Johnson responded directly to Elon Musk's criticism in a post on X.

"Where is the Mike Johnson of 2023!?" Musk posted as he reshared a 2023 post where Johnson talked about concerns on the federal debt.

Johnson responded with a lengthy post.

"The Mike Johnson of 2023 is the SAME Mike Johnson who has always been a lifelong fiscal hawk - who now serves as Speaker and is implementing a multi-stage plan to get our country back to fiscal responsibility and extraordinary economic growth," he said.

"It begins with the critically important One Big Beautiful Bill that includes the LARGEST mandatory spending cut to the federal government in history (by almost 400%), the LARGEST tax cut in history, the LARGEST investment in border security in a GENERATION, along with arguably the STRONGEST collection of pro-growth provisions EVER passed, " Johnson added.

"The same CONSISTENT Mike Johnson who has ALWAYS supported the America First Agenda," the speaker concluded.

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.
