There apparently is some kind of sersious national security threat right now -

The White House's national security adviser said Wednesday that he had already scheduled a classified meeting with congressional leadership before a top House Republican requested that President Joe Biden "declassify all information" that relates to "serious national security threat."

Jake Sullivan, the national security adviser, was pressed several times by reporters at a White House briefing about the Republican request, but he declined to specifically say if Thursday's meeting will be to discuss that reported threat.

He also declined to provide further details about it beyond saying that, broadly, "Americans understand that there are a range of threats and challenges in the world that we are dealing with every single day," such as terrorism.
