Democratic Rep. Zoe Lofgren quietly releases massive social media report on GOP colleagues who voted to overturn the election

Washington (CNN) Democratic Rep. Zoe Lofgren has quietly posted a nearly 2,000-page report documenting social media posts by her Republican colleagues who voted against certifying results of the presidential election on January 6. The information compiled isn't secret, but the report is another sign of the deep distrust that has settled into the US Capitol in the weeks since the insurrection.

The report chronicles the social media activity of members on public forums immediately before the November election and right after the January 6 riot. The report has been online for a week.

CNN reported earlier Thursday that federal investigators are examining records of communications between members of Congress and the pro-Trump mob that attacked the Capitol, as the investigation moves closer to exploring whether lawmakers wittingly or unwittingly helped the insurrectionists.

In a preamble to the report, Lofgren -- the chair of the House Administration Committee -- wrote that she had asked her staff to pull the relevant social media posts and compile them in an effort to gather facts.

"Any appropriate disciplinary action is a matter not only of the Constitution and law, but also of fact," the California Democrat wrote. "Many of former President Trump's false statements were made in very public settings. Had Members made similar public statements in the weeks and months before the January 6th attack? Statements which are readily available in the public arena may be part of any consideration of Congress' constitutional prerogatives and responsibilities."
