Republicans in the Senate will NEVER win if they don't go to a 51 vote majority NOW. They look like fools and are just wasting time...... — Donald J. Trump (@realDonaldTrump) July 29, 2017

....8 Dems totally control the U.S. Senate. Many great Republican bills will never pass, like Kate's Law and complete Healthcare. Get smart! — Donald J. Trump (@realDonaldTrump) July 29, 2017

Thomas Jefferson wrote the Senate filibuster rule. Harry Reid & Obama killed it yesterday. Rule was in effect for over 200 years. — Donald J. Trump (@realDonaldTrump) November 22, 2013

President Trump's repeated calls for Senate Republicans to ram through healthcare reform using the nuclear option conflict with his earlier aversion to the controversial parliamentary procedure.In November 2013, Trump tweeted about his frustration at then Senate Majority Leader Harry Reid after the Nevada Democrat changed the rules to reduce the threshold to end debate on Senate confirmation of certain executive and judicial nominees from 60 votes to 51 votes."Thomas Jefferson wrote the Senate filibuster rule," Trump tweeted . "Harry Reid & Obama killed it yesterday. Rule was in effect for over 200 years."But on Sunday the president urged GOP senators to employ the "nuclear option", so called because the move to curtail the power of filibusters destroyed a long-standing Senate minority protection."Don't give up Republican Senators, the World is watching: Repeal & Replace...and go to 51 votes (nuke option), get Cross State Lines & more," Trump tweeted.The tweet followed two similar missives on Saturday, in which Trump said Senate Republicans would continue to look like fools if they did not permanently amend upper chamber procedures."Republicans in the Senate will NEVER win if they don't go to a 51 vote majority NOW. They look like fools and are just wasting time," Trump tweeted Saturday . "8 Dems totally control the U.S. Senate. Many great Republican bills will never pass, like Kate's Law and complete Healthcare. Get smart!" Trump's renewed agitation with the rule was instigated by the failure of GOP senators Thursday to pass a "skinny" repeal of Obamacare.The president has also sent conflicting messages to Senate Republicans about whether he would be satisfied with a bill that just repealed the Affordable Care Act or whether he would prefer to repeal and replace it.
