The Michigan State Capitol was briefly evacuated and temporarily closed on Thursday as police investigated a possible bomb threat, according to officials.
The State Capitol Facilities Control Office received a call at 6:40 a.m. about the threat at the building in Lansing and notified authorities immediately, state police said in a statement to Fox News.
Officers evacuated staff before entering the building with sniffer dogs and the bomb squad to investigate. The building had already been closed to the public due to coronavirus protocols.

Authorities in Michigan were on high alert on Thursday after more than 300 people protested outside the state capitol building the day before. Those protests came after a mob of pro-Trump supporters forced their way into the U.S. Capitol in Washington, D.C. while Congress was certifying the Electoral College votes for Joe Biden.
