Some U.S. Republican lawmakers joined their Democratic colleagues on Tuesday in criticizing President Donald Trump for labeling them as "treasonous" and "un-American" in response to the cold reception they gave him during his State of the Union address last week.

"Well, that borders on divisive," the second-most powerful Democrat in the Senate, Dick Durbin, told reporters in a purposefully understated tone.

Speaking at a manufacturing plant in Ohio on Monday, the Republican president said Democrats "would rather see Trump do badly than our country do well."
