Senate Minority Leader Mitch McConnell has announced his support for his chamber’s emerging bipartisan gun agreement. The Kentucky Republican's endorsement Tuesday boosted momentum for modest but notable election-year action by Congress on an issue that’s deadlocked lawmakers for three decades.

An outline of the accord was released Sunday by 10 Democrats and 10 Republicans. Leaders hope it can be translated into legislation in days and voted on by Congress before lawmakers' July 4 recess.

McConnell’s backing was the latest indication that last month’s gun massacres in Buffalo, New York, and Uvalde, Texas, had reconfigured the political calculations for some in the GOP.

The House committee investigating the Jan. 6, 2021 riot at the U.S. Capitol has postponed a hearing that was to feature Trump-era Justice Department officials.

The hearing had been scheduled for Wednesday, but the committee on Tuesday morning said it had been delayed. A spokesman for the panel attributed the postponement to “a number of scheduling factors, including production timeline and availability of members and witnesses.”
