CHICAGO (WLS) -- The FBI is warning officials in Washington D.C. and all 50 state capitals to be ready for possible face-offs with violent extremists.
The warning prompted Governor JB Pritzker to activate the Illinois National Guard to bolster security at state buildings in downtown Springfield.
Pritzker has called 250 members for state active duty. Illinois State Police, Secretary of State Police and Illinois Emergency Management Agency are working in tandem with local and federal counterparts to protect the residents of Illinois while safeguarding the right to peaceful protest, according to the governor's office.
Some windows at the State Capitol building were being boarded up Friday.
