HOUSTON, Texas (KTRK) -- A group of activists held a demonstration in downtown Houston Thursday afternoon calling the riots at Capitol Hill "absolutely heinous." About a dozen activists stood in front of the Leland Federal Building on Smith Street calling out President Donald Trump for his response to the riots and protests. Several demonstrators were seen armed, calling it "self-defense." Images from January 6, 2021 "We've seen in the last five years how Trump has mobilized all sorts of factious [supporters] ... they come out in Houston from time to time armed and dangerous, we're here to basically defend ourselves," said Dr. David Michael Smith, one of the organizers and member of Houston United Front Against Fascism.
