The Jan. 6 select committee tasked with investigating the deadly attack at the Capitol is calling for a trio of House Republicans to cooperate voluntarily with its investigation, according to letters sent to the lawmakers on Monday.

The panel, probing the Capitol riots in which supporters of defeated President Donald Trump tried to overturn President Joe Biden's 2020 victory, wants cooperation from GOP Reps. Andy Biggs, Mo Brooks, and Ronny Jackson.

The House committee investigating the Jan. 6 attack on the Capitol sent letters on Monday seeking interviews with three Republican members of Congress, and the panel said it had gathered evidence that some House Republicans sought presidential pardons in the aftermath of the violence that engulfed the Capitol.

A growing number of House lawmakers are calling for a congressional investigation into the inter-agency communication debacle that led to the emergency evacuation of the U.S. Capitol complex on Wednesday evening.

Sandra Day O’Connor and Ruth Bader Ginsburg — the first women to sit on the highest court in the country — are joining the relatively short list of women memorialized as sculptures at the U.S. Capitol. Bipartisan legislation to add statues of the two Supreme Court justices to the Capitol was spearheaded by women lawmakers, passed the Senate last December, passed the House at the end of March and signed by President Joe Biden on Wednesday.

The leaders of the House committee investigating the Capitol attack have grown divided over whether to make a criminal referral to the Justice Department of former President Donald J. Trump, even though they have concluded that they have enough evidence to do so, people involved in the discussions said.

The debate centers on whether making a referral — a largely symbolic act — would backfire by politically tainting the Justice Department’s expanding investigation into the Jan. 6 assault and what led up to it.

Rep. Liz Cheney said Sunday that Congress is mulling whether to issue a criminal referral to the Justice Department against former President Donald Trump for “unlawfully” seeking to obstruct certification of the 2020 election.

Mrs. Cheney, Wyoming Republican, told CNN that the House select committee investigating the Jan. 6, 2021, riot at the U.S. Capitol had uncovered significant evidence that Mr. Trump and aides had acted improperly.

Rep. Liz Cheney said Sunday that the House Jan. 6 select committee has enough evidence to refer former President Donald Trump for criminal charges.

Rep. Liz Cheney (R-Wyo.) on Sunday rejected a report that there is a dispute among members of the Jan. 6 House select committee regarding whether to make a criminal referral for former President Trump.

The New York Times reported that members of the House select committee investigating the Jan. 6 attack on the Capitol are divided over whether to make a criminal referral to the Department of Justice (DOJ) for Trump, even though the panel has determined that they have the evidence for such a move.

President Joe Biden was due to meet with his fellow Democrats in Congress on Friday, as progressives and moderates in his party remained divided over two massive spending bills that account for much of his domestic agenda.

Democrats have struggled to coalesce around those two bills. Progressives have vowed to block a $1 trillion infrastructure bill without an agreement to advance a larger social spending and climate change bill. Moderates say that bill's current $3.5 trillion price tag is too high.

A few hundred protesters gathered around the US Capitol on Saturday, for a rally in support of the pro-Trump rioters who ransacked the building on 6 January.

But the group were easily outnumbered by the police and journalists present.

Ahead of the event, police said they had detected "threats of violence" and security was tightened in Washington.

Organisers had a permit for 700 to attend, but only about 100 to 200 protesters turned up, Reuters reports.
