House Minority Leader Kevin McCarthy on Monday expressed frustration after House Democrats declined his third request for unanimous consent to quickly advance a bill to increase security for Supreme Court justices.

McCarthy has tried several times over the past week to advance the measure — which passed the Senate last month but has stalled in the Democrat-controlled House — after authorities foiled an alleged assassination attempt against Justice Brett Kavanaugh on Wednesday.

“For the 3rd time in a week, I’m calling for a vote for stronger security for Supreme Court Justices—ALL of them,” McCarthy said on Twitter. “This isn’t partisan. The threat is real. Why is Speaker Pelosi blocking something that the Senate has already passed unanimously?”

The Senate passed a bill on May 9 to provide around-the-clock security to the families of Supreme Court justices after the Dobbs vs. Jackson Women’s Health Organization draft leak sparked protests outside of the conservative justices’ homes. While the measure had bipartisan support in the Senate, it has stalled in the Democrat-controlled House as some Democrats have argued the enhanced protections should extend not only to the justices, but to others who work within the Court.

McCarthy said in remarks on Monday that there is “no reason” to further delay.
