Donald Trump’s latest campaign rally was rocked by repeated protests on Wednesday as the US president urged Texas voters to back the embattled Senate candidate Ken Paxton.

Donald Trump’s campaign rallies can be repetitive. Very repetitive. He calls himself the “greatest” president leading the “greatest” movement inside the “greatest” economy. He rails against “Dumocrats” for the “transgender mutilization” of children. He lambasts the “fake news” and reheats election lies. He describes illegal immigration as an “invasion” and recites the poem The Snake.
