The Republican Main Street Partnership PAC — which is supporting a group of 53 moderately conservative members of Congress — will endorse Rep. Steve King’s GOP opponent Randy Feenstra for Iowa’s deeply conservative 4th district.
The group, which advocates for a sizable, if shrinking part of the Republican caucus, is the first national GOP organization to publicly endorse and financially support King’s primary challenger.
The backdrop: King has come under fire from both his Republican and Democratic colleagues on the Hill for racist and xenophobic comments. Some congressional leaders, like House Republican committee chair Liz Cheney (R-Wy.), have called for his resignation.
