Trump schedules Missouri campaign rally for Sept. 13, endorsing Hawley
Trump won Missouri by 18 percentage points in 2016. McCaskill is a top target for Republicans seeking to expand the party’s slim 51-49 edge in the U.S. Senate.
She is among 10 Senate Democrats up for re-election this year in states where Trump won, and is considered among the most vulnerable incumbents.
Trump plans a heavy schedule of campaigning and fundraising through the Nov. 6 midterm elections.
