Houston Police intervened on Monday after a Trump supporter in a "Make American Great Again" baseball cap, KTRK reports.

President Donald Trump flew to Texas to stump for Sen. Ted Cruz (R-TX), who is facing a closer-than-expected campaign by Rep. Beto O'Rourke.

The shoving match became when the Trump supporter entered an area outside the Toyota Center that authorities had set aside for protesters.
