Story highlights Coffman appeared to be the first GOP lawmaker to call for Spicer's ouster

Coffman, a moderate representing a swing district in and around Aurora, was asked at a town hall about Spicer's remarks this week that even Hitler didn't "sink to using chemical weapons" during the Holocaust.

"I need to hear from my congressman that these things are unacceptable," the woman said.
