Update: Cory Booker has now delivered the longest speech in a chamber in history – beating Strom Thurmond’s record.

Democrat Senator Cory Booker (NJ) has been ranting about President Trump and Elon Musk from the senate floor for 24 hours and counting.

A bug-eyed Booker started his marathon rant on Monday evening and he’s still droning on about President Trump as of Tuesday afternoon.

Sen. Cory Booker's (D-N.J.) record marathon speech on the Senate floor won the floundering Democratic Party something it has desperately needed in the Trump era: attention and the applause of its base.

The big picture: Top Democrats believe they are in their deepest hole in nearly 50 years after losing the White House, Senate and House, and the party's base has grown impatient with leaders who haven't countered President Trump more aggressively.

Sen. Cory Booker is holding the Senate floor into Tuesday afternoon, as the New Jersey Democrat continues his marathon speech protesting actions taken by President Donald Trump’s administration.

The Democratic senator vowed Monday evening that he would keep going as long as he was “physically able,” continuing his remarks through the night. As of noon Tuesday, he had spoken for more than 17 hours, having begun at 7 p.m. ET Monday.

New Jersey Democratic Sen. Cory Booker on Tuesday morning was still speaking on the Senate floor, staging a filibuster he started at 7 p.m. Monday night, in what he called a protest against the national "crisis" he said President Donald Trump and Elon Musk had created.

On Monday night, he said he was set to last "as long as [he is] physically able." He has been speaking for more than 15 hours.

The Senate today passed a resolution from the House by a margin of 80-15 to adopt the tentative agreement that railroads and unions negotiated in September under the supervision of the White House. It will now go to President Biden for his signature.

A nationwide freight rail strike that President Joe Biden warned would have decimated the U.S. economy has been averted after the Senate voted overwhelmingly Thursday to impose a tentatively approved labor deal.

The vote was 80-15.

The legislation, which the House passed Wednesday, marked the first time in 30 years that Congress intervened to stop a rail strike. But Biden and bipartisan congressional leaders – reluctantly – said it was imperative the potentially crippling rail strike be prevented.

TOPLINE The Senate approved a new contract between railroad companies and labor unions on Thursday in a last-minute vote, ahead of a December 9 deadline that could trigger a nationwide railroad strike and severely hamstring the economy—but Senators rejected the unions’ demands for paid sick leave.

KEY FACTS The Senate voted 80-15 in favor of an agreement, which was brokered by the Biden Administration in September and includes a 24% raise through 2024.

Sen. Kyrsten Sinema (D-Ariz.) on Monday engaged in a mutual admiration exchange with the Senate Minority Leader Mitch McConnell (R-Ky.), expressed support for restoring elements of the filibuster and suggested that Republicans might win control of the House or Senate in the midterm elections.

Several Democrats were unhappy, criticizing not only her remarks but her timing.

Sen. Kyrsten Sinema (D-Ariz.) on Monday said the Senate should reinstate the 60-vote threshold for all judicial and executive branch nominees.  

Sinema made the comments during a Q&A session following a speech at the McConnell Center at the University of Louisville. Senate Minority Leader Mitch McConnell (R-Ky.) introduced the Arizona moderate at the event. 

Sen. Kyrsten Sinema (D-AZ) defended her support for the filibuster on Monday despite near-unified opposition from the rest of her party, taking the absolutist view that it should even be restored for judicial nominations.

Speaking at the McConnell Center at the University of Louisville in Kentucky, Sinema spoke out against Democratic efforts to scrap the rule, which requires 60 votes to move forward on most legislation.
