"I'm supporting the president that's going to be the most pro-life president."
That's Chiefs kicker Harrison Butker throwing his weight behind Donald Trump ... while at a campaign event in Missouri, for U.S. Senator Josh Hawley, a buddy of the 3x Super Bowl champion.
"The [Pr- life] topic is the most crucial topic for me," 29-year-old Butker said during an appearance on FOX News' The Ingraham Angle on Thursday.
"I want us to be fighting for the most vulnerable, fighting for the unborn, and that's what we should prioritize," Harrison explained.
