U.S. Capitol Police on Thursday asked that the National Guard remain on-site for an additional 60 days due to ongoing security concerns and potential violence at the Capitol, AP reports.

Why it matters: While many lawmakers are eager for security measures surrounding the Capitol — including fencing and an increased law enforcement presence — to be lightened, the request by Capitol Police reflects concerns about ongoing threats.

• Capitol Police announced additional security measures on Wednesday after obtaining intelligence showing "a possible plot to breach the Capitol by an identified militia group on Thursday, March 4."
• The House canceled its session due to further FBI and Homeland Security warnings of a potential threat to the Capitol.

What they're saying: House Speaker Nancy Pelosi said at a press conference on Thursday that she'll leave decisions about the National Guard to security officials.
