Thirteen Senate Democrats sent a letter to Majority Leader John Thune committing to working with Republicans in "good faith" toward providing the necessary 60 votes in the Senate to pass certain immigration measures.

"As we have shown, Democrats and Republicans can work together on real bipartisan solutions. We can solve big challenges when we work together, and there is much work to do to improve border security, protect Dreamers and farmworkers, and fix our immigration system to better reflect the needs of our country and our modern economy," the Democrats wrote.

The group of Democrats say common ground can be reached on "fair immigration enforcement accompanied by the necessary resources to effectively secure our border". They also say they see a need for a "firm but fair immigration system."

A bipartisan border bill was negotiated and unveiled during the 2024 campaign, but was effectively killed by Trump, who urged Republicans not to support it.

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.”

President Donald Trump’s controversial executive order on birthright citizenship will face its first legal test in a Seattle courtroom on Thursday morning.

U.S. District Judge John Coughenour scheduled a 10 a.m. hearing on Thursday to consider a request made by four states to issue a temporary restraining order against Trump’s executive order.

Earlier Tuesday, the attorneys generals of Arizona, Oregon, Washington and Illinois sued Trump over the order, which they said would disenfranchise more than 150,000 newborn children each year.

They described Trump's executive order as the modern equivalent of the Supreme Court's infamous Dred Scott decision. The 14th Amendment repudiated Scott establishing what the plaintiffs called a "bright-line and nearly universal rule" that Trump now seeks to violate.

"President Trump and the federal government now seek to impose a modern version of Dred Scott. But nothing in the Constitution grants the President, federal agencies, or anyone else authority to impose conditions on the grant of citizenship to individuals born in the United States," their emergency motion said.

Coughenour -- who was nominated to the bench by former President Ronald Reagan -- will likely be the first judge to weigh in on Trump’s executive order.
