President Trump on Saturday urged Republican senators to vote on a new healthcare bill to repeal and replace or else become "total quitters."

"Unless the Republican Senators are total quitters, Repeal & Replace is not dead! Demand another vote before voting on any other bill!" Trump wrote.

The tweet was his latest in a string of tweets on healthcare throughout the day Saturday that included urging Senate Majority Leader Mitch McConnell, R-Ky., to go "nuclear" and change the legislative filibuster. He also threatened to withhold payments to insurers -- known as cost-sharing reductions -- in a push to dismantle the Affordable Care Act, which he described as already "imploding."

"Republican Senate must get rid of 60 vote NOW! It is killing the R Party, allows 8 Dems to control country. 200 Bills sit in Senate. A JOKE!" Trump said. "The very outdated filibuster rule must go. Budget reconciliation is killing R's in Senate. Mitch M, go to 51 Votes NOW and WIN. IT'S TIME!"

"After seven years of "talking" Repeal & Replace, the people of our great country are still being forced to live with imploding ObamaCare!" Trump said. "If a new HealthCare Bill is not approved quickly, BAILOUTS for Insurance Companies and BAILOUTS for Members of Congress will end very soon!"

The tweets come two days after three Republican senators -- Sens. John McCain of Arizona, Lisa Murkowski of Alaska, and Susan Collins of Maine -- voted against the "skinny" repeal of the ACA, which led to the bill's demise.
