Sen. Mitt Romney brushed off Democrats for complaining about the Senate’s decision to follow trial rules similar to those used during President Bill Clinton’s impeachment.

Romney, 72, the junior senator for Utah and 2012 Republican presidential nominee, has been one of the few Senate Republicans to question President Trump’s behavior in the events that led to impeachment, but he claimed that Democrats have taken their protests too far. While speaking to CNN on Monday, the Utah senator criticized his Democratic colleagues for opposing Senate Majority Leader Mitch McConnell's version of the impeachment trial rules that were used during Clinton’s impeachment.

“Well, the changes [in the trial rules] are pretty modest and I don’t think are significant in any dramatic way. So for instance, whether something is going to be taking 12 hours per day or eight hours per day, it’s still going to be covered in the news,” Romney said. “And what’s officially going into evidence doesn’t make a big difference because the senators are, of course, free to look at all the information they have that comes from the House.”

He added, “I think the Democrats make a mistake when they cry outrage time and time again. If everything is an outrage, then nothing is an outrage.”

Romney said he would be supportive of hearing testimony from additional witnesses, saying, “I’m interested in hearing from John Bolton, perhaps, among others.”
