St. Louis, MO  (KTRS)  Presidential candidate Donald Trump is making a campaign stop in St. Louis today.

The G-O-P frontrunner is scheduled to speak at noon at the Peabody Opera House in downtown St. Louis. Supporters have been lining up for the event since early this morning.

This campaign stop comes ahead of the Missouri Primary on March 15th.

Meanwhile, former Republican presidential candidate Ben Carson says he and  Trump have “buried the hatchet” after months of political wrangling, and he is endorsing the GOP front-runner’s White House bid.

At a press conference in Palm Beach, Florida on Friday, Carson, who left the race earlier this month, described “two Donald Trumps” – the persona reflected on stage, and a private, “very cerebral” person who “considers things carefully.”

In his introduction to Carson Friday, Trump described the retired neurosurgeon as a “special, special person – special man,” and a “friend” who is respected by everyone.
