WASHINGTON — Majority Leader Mitch McConnell is pushing back against President Donald Trump's calls to end Senate filibusters.
When filibusters of legislation are underway, it takes 60 votes in the 100-member Senate to halt them.
Republicans now control the chamber 51-49. But strong Democratic opposition and some defecting GOP senators have kept Republicans from getting the votes needed to end the shutdown — now in its second day.
McConnell has long defended the filibuster. He says Republicans will welcome it whenever they are returned to the Senate minority.
As the Senate began a rare Sunday session, the Kentucky Republican said: "I support that right from an institutional point of view." But he also said, "The question is, when do you use it."

Trump has made repeated calls this year to end that rule, and did it again Sunday in a tweet.
