Trump 2nd term updates: Trump says USAID is run by 'radical lunatics'

House Speaker Mike Johnson said he "fully" supports President Donald Trump's funding freeze, downplaying the impacts, and noted it'll be temporary and not a "major interruption."

"It is a temporary pause for some programs -- it could be an hourslong pause. It is not a big thing. Some of the programs have already been approved. But what this is a, I believe, a common application of common sense," the speaker said during a fireside chat at the GOP retreat on Tuesday. "We want to make sure that the executive orders of the new president are being fully complied with regard to these programs. I think these would be quick reviews."

"I think it's going to be harmless," he added.

Asked by the reporter if Trump is stretching his executive authorities, Johnson said the president has been "using his executive authority, I think, in an appropriate manner."

Within minutes of the White House freezing billions in federal grants and loans, a federal judge blocked the funding pause from taking effect until next week.

The White House has addressed the buyout plan offered to federal workers on Tuesday, with press secretary Karoline Leavitt calling the payout "very generous."

"American taxpayers pay for the salaries of federal government employees, and therefore deserve employees working on their behalf who actually show up to work in our wonderful federal buildings, also paid for by taxpayers," Leavitt said in a statement. "If they don’t want to work in the office and contribute to making America great again, then they are free to choose a different line of work, and the Trump Administration will provide a very generous payout of 8 months."

Twenty-two states and Washington, D.C., are suing the Trump administration over its plan to pause billions in federal grants and loans.

The federal lawsuit, filed in the U.S. District Court for the District of Rhode Island around the same time that a judge for the U.S. District Court for the District of Columbia temporarily delayed the freeze, argued that Trump exceeded his authority as president by denying funds appropriated by Congress.

"The OMB Directive constitutes a refusal to spend money appropriated by Congress, in violation of the executive’s constitutional authority to administer the law," the lawsuit said.

The state attorneys general argued the funding is necessary to support health systems, Medicaid, law enforcement, disaster relief, critical infrastructure, education systems and other key services.

"Without this funding, Plaintiff States will be unable to provide certain essential benefits for residents, pay public employees, satisfy obligations, and carry on the important business of government," the filing said.

ABC News has obtained the Office of Personnel Management memo sent to government employees Tuesday informing them of their offer for "deferred resignation," which begins effective immediately and offers pay and benefits until Sept. 30 for those who accept.

The memo, titled "Fork in the Road," instructs employees simply to reply "Resign" in the message body if they plan to accept the buyout.

The memo states that any government employee can qualify "except for military personnel of the armed forces, employees of the U.S. Postal Service, those in positions related to immigration enforcement and national security, and those in any other positions specifically excluded by your employing agency."

The last day to accept the offer is Feb. 6, per the memo.
