A day before the Capitol Building was raided the FBI warned that an attack on the DC edifice was being planned out. As we read in USA Today:

The FBI issued a dire internal warning on the day before the Capitol riots that violent extremists were planning an armed uprising in Washington that the attackers described as “war” to coincide with Congress’ counting state-certified Electoral College votes to confirm the election of Joe Biden, The Washington Post reported Tuesday.

The intelligence report, prepared by the FBI’s Norfolk office, described an array of preparations for an assault to include a map of Capitol-area tunnels and staging areas in in Kentucky, Massachusetts, Pennsylvania and South Carolina.

“An online thread discussed specific calls for violence to include stating ‘Be ready to fight. Congress needs to hear glass breaking, doors being kicked in,'” the Post reported, quoting from the document’s contents. “Go there ready for war. We get our President or we die. NOTHING else will achieve this goal.”

It was not immediately clear how widely the warning was shared. The ominous nature of its contents appeared to represent the most serious unheeded alarm in advance of last week’s deadly assault on the Capitol.
