The House select committee on January 6 revealed new text messages written by Fox News host Sean Hannity, asking him to cooperate with the investigation.

In a letter to Hannity released publicly on Tuesday, chairman Benny Thompson called the Fox News host a "fact witness" to the investigation.

Thompson noted how Hannity was 'expressing concerns and advising the president and some White House staff' about January 6th.

He also sent press coverage of the cabinet to Chief of Staff Mark Meadows, threatening to remove President Donald Trump using the 25th Amendment.

Thompson asked Hannity to sit in front of committee members for a written interview and not to destroy any communication with officials.

Hannity failed to mention his request for cooperation on Tuesday night.

Sean Hannity has dubbed Washington DC officials 'elected swamp creatures and sycophants' as he hit out at his 'repulsive' failure to act while 'Biden mismanaged COVID-19'.

The Fox News host launched Broadside after failing to mention his text messages to Donald Trump's staff prior to the Capitol riot, which were revealed by a January 6th House committee.

Hannity wrote on the eve of the deadly siege, 'I am deeply concerned about the next 48 hours.

The committee, in a letter to Hannity on Tuesday, demanded that he appear before Congress as a "fact witness" in its investigation, noting how Fox Star was "expressing concern and the President and the White House." Was advising the employees.

Instead, Hannity lashed out at DC executives and their "willing allies" on her show last night.

“I have an important message for all you selected swamp creatures in Washington, DC, your willing colleagues, your press secretaries in the media crowd,” he began.

'It's obviously repulsive, just repulsive that you all sycophancy, you sit idly by, you say nothing, you do nothing, because Joe Biden completely mismanages COVID-19.'

Hannity's lawyer, Jay Sekulow, said earlier in the day that he was reviewing the letter and "will give an appropriate response."

Text messages show that Hannity wrote on the night of January 5, 'I am very worried about the next 48 hours.'

He also sent White House chief of staff Mark Meadows media reports "related to a possible attempt by members of President Trump's cabinet to remove him from office under the 25th Amendment," Thompson's letter revealed.

Less than a week earlier, on 31 December, Hannity told Meadows: 'We can't afford to lose the entire WH council office. I don't see January 6 as happening the way they are being told.

After '[6th] he should announce that he will lead a nationwide effort to improve voting integrity. Go to Fl and watch Joe Mes Up daily. Stay on. People will listen when he speaks,' Hannity continued.

In the letter, Thompson said, 'The text suggests that you had knowledge of the concerns raised by President Trump's Office of the White House Council about the legitimacy of the former President's January 6 plans.'

"These facts are directly related to our investigation," Thompson told Hannity.

On January 5, on the eve of the Capitol attack, Hannity also wrote to Meadows, 'Pence pressure. WHO's lawyers will leave.

'What communication or information led you to conclude that the White House attorney would be leaving? What did you really know at that time?' Thompson asked.

Thompson also said that Hannity appeared to have "extensive information about President Trump's state of mind in the days following the January 6 attack."

One of Hannity's texts indicated that she had discussions with Trump on January 10 and this left the Fox News host in the lead-up to the January 20 inauguration of President Joe Biden.

"Guys, we have a clear path to land the plane in 9 days," Hannity informed Meadows and Republican Representative Jim Jordan.

'He cannot mention re-election. Sometimes. I didn't get to meet him well today. And even worse, I'm not sure what's left to do or say, and I don't like knowing if it's really understood. Idea?'

Axios first reported Tuesday that Hannity would be asked to cooperate with the investigation.

Hannity's attorney Sekulow told the publication: 'If this is true, then any such request would raise serious constitutional issues, including First Amendment concerns regarding freedom of the press.'

A Fox News spokesperson referred DailyMail.com to Sekulo's comments when asked if Hannity had a response from the committee.

Thompson's letter said, "The Select Committee has great respect for the First Amendment to our Constitution, the freedom of the press, and the rights of Americans to freely express their political views."

For this reason, we do not intend to receive information from you about your broadcasts on radio or television, your public reporting or commentary, or your political views about any candidate for office.

Thompson said before asking questions about individual texts, 'Thus, we write today to seek your voluntary cooperation on a specific and narrow range of factual questions.

The committee's access to text messages came from a set of documents submitted by Meadows, who has said he will no longer cooperate with the investigation.

Thompson asked Hannity to sit for a written interview with the selection committee.

It also asked him to preserve all records of communication with the persons involved on January 6.

We have no doubt that you love our country and respect our Constitution. Now is the time to move forward and serve the interests of our country. We thank you in advance for your cooperation,' Thompson's letter concluded.
