The president's Twitter attack came after Sasse told constituents in a telephone town hall Wednesday that Trump has “flirted with white supremacists,” mocks Christian evangelicals in private, and “kisses dictators’ butts.”
Trump tweeted that Sasse is “the least effective of our 53 Republican Senators, and a person who truly doesn’t have what it takes to be great.”
Trump's tirade continued throughout the day as he compared Sasse to former U.S. Sens. Bob Corker of Tennessee and Jeff Flake of Arizona, who left the Senate after combative relationships with the president. Trump suggested perhaps Republicans should find “a new and more viable candidate?”
Trump carried Nebraska by 25 percentage points in 2016.
Sasse “said the same thing to Nebraskans that he has repeatedly said to the President directly in the Oval Office,” spokesman James Wegmann said in a statement Saturday. "Ben is focused on defending the Republican Senate majority, and he’s not going to waste a single minute on tweets.”
