What about other speakers?

Before Mr. Trump spoke at the “Stop the Steal” rally, other speakers warmed up the crowd by angrily repeating false claims that the election had been stolen, making assertions that have come under scrutiny in light of the subsequent violence.

Representative Mo Brooks, Republican of Alabama, shouted, “Today is the day American patriots start taking down names and kicking ass!” Donald Trump Jr. warned Republican lawmakers who did not back his father’s effort to overturn the election: “We’re coming for you.” And Mr. Trump’s personal lawyer Rudolph W. Giuliani declared, “Let’s have trial by combat” — a practice from the Middle Ages of settling disputes by fighting.

The New York State Bar Association said on Monday that it was opening an inquiry about whether to remove Mr. Giuliani from its membership, citing a bylaw against membership by people who advocate using force or other illegal means to try to overthrow the government.
