Why Trump appears deeply unnerved as Capitol attack investigation closes in

Donald Trump is increasingly agitated by the House select committee investigating the Capitol attack, according to sources familiar with the matter, and appears anxious he might be implicated in the sprawling inquiry into the insurrection even as he protests his innocence.

The former president in recent weeks has complained more about the investigation, demanding why his former White House chief of staff, Mark Meadows, shared so much material about 6 January with the select committee, and why dozens of other aides have also cooperated.

Trump has also been perturbed by aides invoking the Fifth Amendment in depositions - it makes them look weak and complicit in a crime, he has told associates - and considers them foolish for not following the lead of his former strategist Steve Bannon in simply ignoring the subpoenas.

When Trump sees new developments in the Capitol attack investigation on television, he has started swearing about the negative coverage and bemoaned that the House minority leader, Kevin McCarthy, was too incompetent to put Republicans on the committee to defend him.

A spokesperson for Trump did not respond to requests for comment.

But as Trump struggles to shield himself from the select committee, with public hearings next year and the justice department said to be tracking the investigation, the path ahead is only likely to be more treacherous.

The former president is especially attuned to his potential for legal exposure, even as he maintains he did nothing wrong in conferring about ways to overturn the 2020 election and encouraging supporters to march on the Capitol. He has expressed alarm to associates about repeated defeats in court as he seeks to stop the select committee obtaining some of the most sensitive of White House documents about 6 January from the National Archives, on grounds of executive privilege.
