WASHINGTON (WJW/AP) — The U.S. Capitol Police say they have intelligence showing there is a “possible plot” by a militia group to breach the U.S. Capitol on Thursday.

The revelation was detailed in a statement from the Capitol Police. It comes at the same time the acting police chief is testifying before a House subcommittee.

The statement says:

“The United States Capitol Police Department is aware of and prepared for any potential threats towards members of Congress or towards the Capitol complex. We have obtained intelligence that shows a possible plot to breach the Capitol by an identified militia group on Thursday, March 4. We have already made significant security upgrades to include establishing a physical structure and increasing manpower to ensure the protection of Congress, the public and our police officers.

Our Department is working with our local, state, and federal partners to stop any threats to the Capitol. We are taking the intelligence seriously. Due to the sensitive nature of this information, we cannot provide additional details at this time.”

The statement differs from an advisory that was sent to members of Congress by the acting House sergeant-at-arms this week, saying that Capitol Police had “no indication that groups will travel to Washington D.C. to protest or commit acts of violence.”

The threat comes nearly two months after thousands of supporters of then-President Donald Trump stormed the U.S. Capitol in a violent insurrection as Congress was voting to certify Joe Biden’s electoral win. So far, about 300 people have been charged with federal crimes for their roles in the riot. Five people, including a Capitol Police officer, died.

The threat appears to be connected to a far-right conspiracy theory, mainly promoted by supporters of QAnon, that Trump will rise again to power on March 4, which was the original presidential inauguration day, until 1933, when it was moved to Jan. 20.

Many of the accounts that helped promote and organize the Jan. 6 riots on platforms like Facebook and Twitter have since been suspended, making it more difficult for the groups to organize.
