McCarthy Threatens Technology Firms That Comply With Riot Inquiry

The top House Republican said his party would retaliate against any company that cooperated with an order to preserve the phone and social media records of G.O.P. lawmakers.

WASHINGTON — Representative Kevin McCarthy, the House Republican leader, has threatened to retaliate against any company that complies with the congressional committee investigating the Jan. 6 riot, after the panel asked dozens of firms to preserve the phone and social media records of 11 far-right members of Congress who pushed to overturn the results of the 2020 election. Mr. McCarthy’s warning was an escalation of his efforts to thwart a full accounting of the deadly attack at the Capitol carried out by a pro-Trump mob, and his latest attempt to insulate the former president and Republican lawmakers from scrutiny of any ties to the violence. It came after he led the G.O.P. opposition to the creation of an independent bipartisan commission to investigate the riot, and then pulled five Republican congressmen from the select committee that Democrats created on their own, boycotting the proceedings. In preservation orders the special committee sent to 35 technology firms this week, members of the panel included the names of hundreds of people whose records they might want to review, among them some of Donald J. Trump’s most ardent allies in Congress, according to several people familiar with the documents who were not authorized to speak about their contents.
