Led by Oregon Sen. Jeff Merkley, Democrats seized the Senate floor on Wednesday to protest President Donald Trump’s presidency amid the government shutdown and push for Republicans to negotiate with them on expiring health subsidies.

Merkley spoke for more than 22 hours — from 6:21 p.m. Tuesday to 5:00 p.m. on Wednesday — pausing for lengthy questions from other Democratic senators. His speech was one of the longest in Senate history, just short of a similar speech in April by Sen. Cory Booker of New Jersey.

Booker, who was also protesting Trump, broke the record for longest continuous Senate speech by going for more than 25 hours, surpassing a 1957 speech by Sen. Strom Thurmond of South Carolina. Thurmond was filibustering the advance of the Civil Rights Act.

The senator’s talk-a-thon came as Democrats have forced the government shutdown over their demands to extend government health care subsidies, and as Republicans have refused to negotiate over the expiring tax credits until Democrats vote to reopen the government.

Democrats have voted 12 times to keep it closed — most recently Wednesday evening — and the two sides have made little progress toward a resolution.

Merkley said on the Senate floor that Republicans were the ones shutting down the government “to continue the strategy of slashing Americans’ health care” after passing cuts to Medicaid and other programs over the summer.

He used several hours of his speech to describe what he said were Trump’s authoritarian moves, including attacks on the press and policies that Democrats say are enriching billionaires at the expense of regular people. He said that Trump’s plan is to replace a government “by and for the people with a government by and for the powerful.”
