WASHINGTON — Senate Majority Leader Mitch McConnell on Thursday slammed Sen. Chuck Schumer over his “astonishingly reckless and complete irresponsible” threats toward two Supreme Court justices.

In a lengthy rebuke on the Senate floor, McConnell accused Schumer of trying to “incite violence on the steps of the Supreme Court” after he warned conservative Justices Neil Gorsuch and Brett Kavanaugh would “pay the price” if they voted to restrict abortion rights.

“The United States Senator threatened the Supreme Court justices. Period. There’s no other way to interpret that,” McConnell said.

“At the very best his comments were astonishingly reckless and completely irresponsible,” he added.

Schumer’s comments, made at an abortion rights rally outside the court as it heard a Louisiana abortion case, were met with a rare reprimand from Supreme Court Chief Justice John Roberts.

“Justices know that criticism comes with the territory, but threatening statements of this sort from the highest levels of government are not only inappropriate, they are dangers,” Roberts wrote in a statement.

“All Members of the Court will continue to do their jobs without fear or favor, from whatever quarter,” he concluded.

But Schumer spokesman Angelo Roefaro said Roberts had followed “the right wing’s deliberate misinterpretation” of the New York senator’s comments.

“Sen. Schumer’s comments were a reference to the political price Senate Republicans will pay for putting these justices on the court, and a warning that the justices will unleash a major grassroots movement on the issue of reproductive rights against the decision,” Roefaro said.

On Twitter on Wednesday evening, President Trump warned Schumer should “pay a severe price” for his comments.

“There can be few things worse in a civilized, law abiding nation, than a United States Senator openly, and for all to see and hear, threatening the Supreme Court or its Justices,” Trump wrote.
