The US House of Representatives Committee investigating last year's attack on the Capitol Building by Donald Trump supporters has said it wants to question Fox News TV host Sean Hannity about the events.
The committee chairman said they wanted to discuss his text message exchanges with the former president and his Chief of Staff.
Legislators said in a letter that they have obtained "dozens of text messages" that Mr Hannity, a star host at Fox News channel and a regular guest at Trump rallies, sent to the former president and his entourage before the attack.
On 6 January last year, thousands of Trump supporters stormed the seat of US democracy in a bid to prevent lawmakers from certifying President Joe Biden's victory.
Five people were killed in the melee and scores were injured.
"I'm very worried about the next 48 hours," Mr Hannity wrote in one of those text messages on the eve of the attack, according to the legislators' letter to Mr Hannity.
"Why were you concerned about the next 48 hours?" Representatives Bennie Thompson and Liz Cheney, who head the investigative committee, asked Mr Hannity in their letter.
They asked Mr Hannity to schedule a time for a transcribed interview with the committee.
Tomorrow, Mr Biden will deliver a speech commemorating the attack in which he is expected to warn of a significant threat to political freedoms that until now most Americans took for granted.
Meanwhile, Mr Trump has cancelled plans to hold a news conference tomorrow to mark the event.
Mr Trump said in a statement he was cancelling the event at his Mar-a-Lago resort in Florida "in light of the total bias and dishonesty" of the congressional committee probing the assault by his supporters, and of the media.
