Trump 2nd term live updates: Trump defends tariffs, declines to comment on Ukraine aid

"After speaking with President Claudia Sheinbaum of Mexico, I have agreed that Mexico will not be required to pay Tariffs on anything that falls under the USMCA Agreement," President Donald Trump wrote on his conservative social media platform. "This Agreement is until April 2nd. I did this as an accommodation, and out of respect for, President Sheinbaum."

"Our relationship has been a very good one, and we are working hard, together, on the Border, both in terms of stopping Illegal Aliens from entering the United States and, likewise, stopping Fentanyl. Thank you to President Sheinbaum for your hard work and cooperation!" Trump added.

The White House has pulled Thursday's signing of the executive order to dismantle the Department of Education, multiple sources told ABC News.

White House Press Secretary Karoline Leavitt quoted a news report saying it was "fake news" that Trump was expected to sign the order Thursday. She said he is not signing it.

Behind the scenes, there was concern among top administration officials about the blowback the order would receive and the lack of messaging in place ahead of the rollout.

Specially, how the administration would answer questions about how the EO would impact the school lunch program along with other programs that could no longer exist.

A coalition of non-profit groups suing the Trump administration over its foreign aid freeze asked a federal judge to impose a deadline of Monday, March 10, at 5:59 p.m for the government to pay more than $1.5 billion owed to them, according to court papers filed Thursday -- a timeline that Trump administration attorneys called "not feasible."

After a divided Supreme Court ruled Wednesday that the Trump administration must comply with a district court order to execute those payments, the federal judge overseeing the case asked the parties to propose a payment schedule ahead of an in-person hearing on Thursday afternoon.

The coalition of nonprofits and the Trump administration wrote Thursday morning that "they were unable to come to an agreement."

The administration pledged to "proceed expeditiously" but must "also hold an obligation to the public to ensure that taxpayer funds are spent only for legitimate work that was actually performed." They suggested that these payments could be completed in "not more than ten working days."

Attorneys for the coalition of aid groups, in their own statement, accused the Trump administration of continuing "to erect barriers to compliance with their payment obligations."

A federal judge denied a request on Thursday from USAID contractors to issue a temporary restraining order blocking the mass termination of their contracts.

The Personal Service Contractor Association, an advocacy group for U.S. personal services contractors employed by USAID, filed a lawsuit against the Trump administration last month after the secretary of state issued a stop-work order for all foreign assistance and contracts.

The contractors alleged the stop-work order prevented the association's members from carrying out work for "which their positions were created and exist by law and from overseeing often lifesaving humanitarian relief."

According to the complaint, the contractors were "irreparably injured" because they say the stop-work order cut "essential communication and network access, endangering their personal safety and security" and water and electricity for their homes overseas due to the funding freeze.
