We have seen some Republicans pushback against Donald Trump’s outlandish claims that Democrats are somehow trying to “steal the election.” But this may be the strongest yet. It comes from Rep. Adam Kinzinger (R-IL) who tweeted this in response to one of the president’s tweets that Twitter flagged as misleading).

And here’s what Kinzinger said today on CNN:

“It’s one thing for a president to kind of declare that he thinks he’s going to win or even declare victory. that’s a bit much, shouldn’t do it. Where I have a real problem with what’s going on is when a president starts alleging voter fraud without evidence of that…” 

“The problem with throwing out unsubstantiated charges is it undermines faith in democracy and then when he loses or maybe even when you win, people aren’t going to believe it. I will tell you what, I looked at Facebook last night before I went to bed, which was a mistake, just to look at it, and I just — every one of the stories on my wall were somebody that believed that either 100,000 votes were dumped with only Biden’s votes or that Wisconsin had more voters than people registered to vote. None of it is true, but people believe this. this is how this stuff gets spread.” 

Zinkinger also told ABC News that it’s not acceptable to “undermine the integrity of an election system without presenting the proof.”
