SUN CITY, Ariz.—U.S. Senate candidate Blake Masters said Congress should impeach President Joe Biden for his role in the illegal migrant crisis resulting in a flood of fentanyl across the southern border into the United States.

At the same time, Trump-endorsed Masters, a Republican, said his incumbent opponent, Democrat Mark Kelly, has done little to stem the national security crisis since he took office and should be held accountable.

“Where’s Mark Kelly on this? I think Mark Kelly should have to attend some of the funerals of the [fentanyl victims] on this,” said Masters during a Republican gathering in Sun City, Arizona, on Oct. 1.

“Do you ever get the feeling they’re doing this on purpose?” Masters said.

A crowd of over 400 people attended the event sponsored by the Sun City West Republican Club, during which former Arizona U.S. Senate 2022 primary candidate Jim Lamon voiced support for Masters’ run for Congress.

“This is a huge election for this country,” Lamon said. “We all have to stand united—just like the Marxists, right? They all stand united.”
