Senate Majority Leader Harry ReidHarry Mason ReidTrump thanks Reid for warning Democrats not to underestimate him Reid warns Democrats not to underestimate Trump Harry Reid predicts Trump, unlike Clinton, won't become more popular because of impeachment MORE (D-Nev.) and Minority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellTrump urges GOP to fight for him Senate Dems signal they'll support domestic spending package Trump's top picks for Homeland Security chief are ineligible for job: reports MORE (R-Ky.) late Friday night clashed over when to vote on Reid's debt ceiling plan, as McConnell said Republicans would support an immediate vote, but Reid objected to the Republican demand for a 60-vote threshold for passage.

Just before Reid filed cloture on his bill, McConnell said House Republicans are planning a 1 p.m. vote Saturday on the Reid proposal, and said he would be "more than happy" to allow the Senate to vote before, on Friday night.

In response, Reid said Democrats would be happy to vote Friday if the Senate can approve it by majority vote, "just like the House" voted earlier in the day. Reid here was essentially asking Republicans to drop the threat of filibuster, by which they would force a 60-vote supermajority on cloture and allow the Senate to proceed to the bill.

When McConnell objected, he said it's "obvious" to the world that Republicans are filibustering the bill, and said he's "disappointed."

McConnell said he is having an "out of body experience," since Reid was requesting a simple majority vote on "a matter of this magnitude."

Later, McConnell said this has created a "rather curious position" that the House will now vote on Reid's proposal before the Senate does. The earliest the Senate can vote on Reid's bill is early Sunday morning.
