Former Rep. Mark Schauer (D-Mich.) was hit with pepper spray while protesting "right to work" legislation outside the Michigan state capitol on Wednesday.
“I immediately began to retreat and began to cover my eyes and my mouth,” he told the Battle Creek Enquirer. “It was not good."
Meanwhile, Fox News contributor Steven Crowder was punched repeatedly in an altercation with one protester.
Schauer served one term; he beat Rep. Tim Walberg (R) in 2008 only to lose to the former congressman two years later.
Tear gas was sprayed at least once, according to the Detroit Free Press. At least two people were arrested for trying to force their way into the George W. Romney building, where Gov. Rick Snyder (R) has an office. The governor has pledged to sign the contentious legislation, a final version of which passed the state House on Wednesday.
Tensions flared earlier in the day as pro-union protesters appear to have torn down a tent maintained by Americans for Prosperity, a group backed by the billionaire Koch brothers that was rallying in support of "right to work."
"They couldn't engage in a civil debate, and it's very unfortunate," Scott Hagerstrom, executive director of AFP-Michigan, told the Detroit News.
