LANSING — A top federal prosecutor in Michigan on Thursday urged people to give tips to the FBI if they are aware of people who joined a violent mob that stormed the U.S. Capitol in an attempt to overturn the presidential election.

U.S. Attorney Matthew Schneider, whose jurisdiction covers a 34-county area including metropolitan Detroit, said investigators will review video footage and other evidence. Six Michigan men ranging in age from 25 to 64 were arrested by D.C. police — four for curfew violations, one for unlawful entry and violating the curfew, and one on gun charges.

Those types of crimes will be prosecuted by the U.S. attorney for Washington, D.C., Schneider said. But more serious charges — destruction of property over $1,000, inciting a riot, civil disorder, sedition, using a destructive device like a pipe bomb — could potentially be handled in Michigan, he said, if there are connections to the state.

“It looks like the acts took place in Washington, D.C. But it’s under review right now — what’s the connection of the people in D.C. to the people in Michigan? That’s going to take time to figure out,” Schneider said. “I’m personally disgusted and horrified by this. It’s just nauseating to me. It’s sick what people did inside the Capitol.”

D.C. police said Thursday that 68 people were arrested, while Capitol police said 14 were arrested, most for unlawful entry. More than 50 Capitol and D.C. police were injured, including several who were hospitalized.

“If you’re aware of people who might have traveled from Michigan to go to Washington, D.C., to commit acts of violence, then that could potentially be a federal crime,” Schneider said. “There’s a big difference here between peaceful protests and acts of violence. … Just because people traveled to Washington, D.C., doesn’t necessarily make them criminals.”

Meshawn Maddock, who is expected to be elected the next co-chair of the state Republican Party, told a crowd in the nation’s capital on Tuesday — a day before the violence — that at least 19 busloads of supporters of President Donald Trump were traveling there from Michigan. Her husband, state Rep. Matt Maddock, also spoke and was among GOP state lawmakers who unsuccessfully asked Vice President Mike Pence to delay confirmation of Democrat Joe Biden’s win.

It was unclear if Matt Maddock joined protesters at the Capitol on Wednesday, but Meshawn Maddock retweeted a video of marchers and called it “the most incredible crowd and sea of people I’ve ever walked with.” Trump told a morning crowd near the White House that he would go with them to the Capitol, but he did not. Instead he sent them off with incendiary rhetoric.

Some Democratic legislators said Matt Maddock should be censured, while the national Democratic Legislative Campaign Committee called for his resignation or removal from office. Lynn Afendoulis, spokeswoman for Republican House Speaker-elect Jason Wentworth, said he “hasn’t seen any action on Rep. Maddock’s part that rises to the level of disciplinary action.”

After being criticized by the state Democratic Party, Meshawn Maddock issued a statement to condemn the violence and Capitol breach. “The rally was supposed to be a peaceful event and people who broke the law should be held accountable,” she tweeted.

Incoming House Democratic Leader Donna Lasinski wrote a letter to Wentworth saying 18 House Republicans who wrote to Pence or joined lawsuits challenging Biden’s victory — nearly a third of the caucus — should disavow their actions or face discipline, “up to and including not seating them in the 101st Legislature without disavowing their support of unproven conspiracy theories and actions, undermining our democracy and encouraging the violent overthrow of our government.”
