In the hours after President Donald Trump's second inauguration, the American Federation of Government Employees, the largest union for federal employees filed a lawsuit against Trump and the Office of Management and Budget, while also calling on Congress to protect government workers' jobs.

The lawsuit alleges that the Department of Government Efficiency (DOGE) violates the Federal Advisory Committee Act (FACA).

"DOGE has already begun developing recommendations and influencing decision-making in the new administration, even though its membership lacks the fair balance required by FACA and its meetings and records are not open to public inspection in real time," the complaint alleges.

AFGE National President Everett Kelley has also gone on the offense over Trump's flurry of executive orders to eliminate federal telework and diversity programs, to freeze federal hiring and to re-introduce at-will employment policies that would make it easier to fire some federal employees.

Kelley asked Congress to intervene to save federal workers from being fired at will.

"AFGE will not stand idly by as a secretive group of ultra-wealthy individuals with major conflicts of interest attempt to deregulate themselves and give their own companies sweetheart government contracts while firing civil servants and dismantling the institutions designed to serve the American people," Kelley said in a statement.

He added, "This fight is about fairness, accountability, and the integrity of our government. Federal employees are not the problem-they are the solution. They deserve to have their voices heard in decisions that affect their work, their agencies, and the public they serve."

When asked whether he will "turn off the tap" when it comes to sending weapons to Ukraine, Trump told reporters Tuesday that he is "looking at that."

"We're talking to Zelenskyy. We're going to be talking with President Putin very soon, and we'll see what, how it all happens," Trump said during a briefing in the Roosevelt Room.

Trump added that the European Union should be supporting Ukraine more, saying the war affects them more than the United States.

All federal employees working on Diversity, Equity and Inclusion (DEI) programs and initiatives must be put on paid administrative leave by Wednesday at 5 p.m., according to an Office of Personnel Management memo obtained by ABC News.

The decision comes as the Trump administration shuts down the relevant DEI offices and programs across the federal government.

The directive follows President Donald Trump's signing of executive orders Monday to dismantle federal DEI programs, as part of Trump's larger campaign vow to reverse and upend the diversity efforts across the country, in the public and private sectors.
