Republicans have launched an unprecedented effort to hold the Senate floor and talk for days about a bill that they know won't pass — an attempt to capture public attention on legislation requiring stricter voter registration rules as President Donald Trump pressures Congress to act before November's midterm elections. The talkathon began Tuesday and could last a week or longer as Senate Majority Leader John Thune tries to navigate Trump's insistence on the issue and Democrats' united opposition. The legislation would require Americans to prove they are U.S. citizens before they register to vote and to show identification at the polls, among other new voting requirements.

President Donald Trump is calling on the Senate to scrap the filibuster. That's so the Republican majority can bypass Democrats in the Senate and reopen the federal government. But the GOP leaders swiftly rejected the idea, putting them at odds with the president. Trump targeted the 60-vote threshold for passing legislation in a social media post, suddenly inserting himself into the shutdown debate. But Senate Majority Leader John Thune has strongly opposed changing the filibuster and his spokesman says that position remains unchanged. House Speaker Mike Johnson also panned the idea.
