Just hours before chaos broke out at a postponed Donald Trump rally in Chicago, GOP Sen. Mark Kirk (R-IL) said on Friday that he would support Trump’s candidacy for president if he turns out to be the Republican nominee, bucking a trend among his fellow Illinois Republicans who fear that aligning with Trump will cost them re-election.

Kirk hasn’t endorsed a presidential candidate and has previously attacked Trump. But when asked by a local NBC affiliate if he would support Trump should he be the GOP nominee, Kirk — who is in a tight re-election bid against Iraq war veteran Rep. Tammy Duckworth (D) — said yes. “If he was the nominee I certainly would.” Watch the clip:


The Chicago Tribune reported that Illinois Republican leaders “are expressing cautious concerns over how [Trump’s] nomination could affect GOP chances in the fall” and two GOP congressmen from Illinois — a traditionally Democratic state — have already said they would never support him.

Indeed, crowds of protesters showed up at a Trump rally in Chicago on Friday and the GOP frontrunner was eventually forced to postpone it due to security concerns.

While it’s unclear how Senate Majority Leader Mitch McConnell will handle the Trump issue, he has reportedly “laid out a plan that would have lawmakers break with Mr. Trump explicitly in a general election.”

“We’ll drop him like a hot rock,” McConnell said. Kirk, apparently, doesn’t feel the same way.
