And the purge of Twitter and Facebook accounts promoting violent protests has made it difficult for the public to understand the extent of the issue.
Here’s a look at how a number of states are preparing:
Michigan bans open-carry at Capitol
However, the policy change only affects public areas inside the building and does not change policy on the Capitol grounds, nor does it prohibit licensed concealed pistol carry that follows state laws, according to the commission policy.
“The Capitol Commission’s action to ban open carry guns at the Capitol is a good start, but more action is needed,” Whitmer said in a statement Monday.
Michigan Attorney General Dana Nessel warned that the commission’s rule does not mean the Capitol is safe.
Nessel told CNN’s Erin Burnett that lawmakers are “sitting ducks.”
“I’m exceedingly worried,” she told CNN. “I think you could certainly say that Michigan is ground zero for those who are wishing to take over a state government.
Shanon Banner, spokesperson for Michigan State Police, said they are aware of the march on state capitols being promoted online, and they will continue watching for security threats.
“Our security planning is fluid and adjustments are made as needed, from day-to-day,” Banner said. “Security enhancements that can be put in place include both seen and unseen measures. In general, we don’t discuss security measures, but I can confirm that out of an abundance of caution, we are increasing our visible presence at the Capitol for the next couple of weeks starting today.”
Lansing Mayor Andy Schor also asked Gov. Whitmer to activate the Michigan National Guard to provide additional security and crowd control measures around the state Capitol on Sunday and on Inauguration Day.
“Last week’s horrific scene on Capitol Hill was an attack on our democracy and shows that we need to be adequately prepared for acts of violence as President-elect Joe Biden is sworn in as our 46th President of the United States.”
Wisconsin authorizes state National Guard
Democratic Gov. Tony Evers has authorized the state National Guard to support Capitol Police in Madison, the governor’s office said in a news release Monday.
“Members of the Wisconsin National Guard will mobilize to state active duty to support safety and security efforts at the State Capitol in Madison,” read the release. “The Wisconsin National Guard will serve in a support role to local authorities and conduct a site security mission.”
According to the release, the troops are trained to respond to requests for assistance on short notice and are part of the Wisconsin National Guard Reaction Force.
“The mobilized troops will serve in a State Active Duty status in support of the Capitol Police. To protect operational security, the Wisconsin National Guard will not discuss troop numbers, movements, timelines, equipment, tactics, or procedures.”
In addition, first-floor windows at the Capitol in Madison were boarded up on Monday ahead of potential protests.
Pennsylvania says Capitol is closed to public
A spokeswoman for Gov. Tom Wolf, a Democrat, said they were aware of the planned protests but noted that the state’s Capitol Complex in Harrisburg has been closed to the public since December because of the pandemic.
“The Capitol Police will continue to work with state and local law enforcement to maintain peace at the Capitol Complex in Harrisburg,” press secretary Lyndsay Kensinger said.
“Pennsylvania Guard members are well-trained and well-prepared to assist our communities, commonwealth and country in any way they can,” said acting Adjutant General Maj. Gen. Mark Schindler. “We are also very fortunate that our Guard members have extensive experience working alongside the DC National Guard as part of past training events and presidential inaugurations.”
On Tuesday, Wolf said they “have not heard anything specifically” about protests but are “ready for anything that might happen.”
Georgia opens legislative session with security
The state began its 2021 legislative session on Monday with heightened security around the building, including a new fence and armed guards.
The Georgia Bureau of Investigation (GBI) said it is aware of the reports of possible armed protests in the coming days.
“We are in communication with our partners and will continue to do what is necessary to ensure safety and security,” GBI Public Affairs Director Nelly Miles said.
Atlanta Police said they, too, are working with their partners on security.
“The City of Atlanta Police Department (APD) continues to coordinate with local, state, and federal law enforcement agencies to respond should protests or illegal activity occur. If activity begins to occur, APD is prepared to respond quickly. We do not share operational or security plans. However, the safety and security of our city and citizens is our priority,” police said.
Virginia closing Capitol Square
This year, in anticipation of protests over the next week, a state of emergency was declared in Richmond. The Richmond City Council voted Monday evening to adopt a resolution that allows Mayor Levar Stoney to use a state law that lets him tap into state resources to help with security.
Virginia’s Capitol Square in Richmond will be closed for at least a week starting Thursday, in preparation for possible “civil unrest” around the city, the Department of General Services (DGS) said in a statement.
The “precautionary measures” include closing the Capitol Square, installing fencing and fortifying buildings in and adjacent to the square, the department said. Access to DGS-controlled buildings will be restricted from Saturday through Thursday, they added.
Florida tells Senate staff to work from home
In Florida, President of the Senate Wilton Simpson asked Capitol staff and lawmakers to work remotely on Sunday because it is “very likely” there will be protesters in Tallahassee that day.
The letter, sent to Florida senators and obtained by CNN, says law enforcement has made “significant enhancements” to the Senate’s physical security that will remain confidential.
“I want you all to know that security, as it relates to both the health and safety of our professional staff, our Senators, and visitors is my top priority,” Simpson wrote.
“At this time, it is our understanding that our Capitol remains secure and there have been no threats to our safety,” he added.
Florida Gov. Ron DeSantis said the state will respond quickly to any issues but declined to provide specific security plans.
“If anything is disorderly, we are going to act very quickly. Don’t worry about that,” DeSantis said.
