Iowa was one of the first states in the country to pass legislation against teaching that the United States is systemically racist — an idea some equate with “critical race theory.” But when one social studies teacher asked how he could teach U.S. history without running afoul of the new law, he didn’t get any clarity — or help.

What happens when legislation targets teachers? And as America’s teacher shortage grows — what will this mean for the country’s kids?

Guest: Greg Wickenkamp, former eighth grade social studies teacher in Fairfield, Iowa.
