President-elect Donald Trump‘s Twitter fingers just won’t quit.

Last night, Trump launched a tweet attack on a CNN reporter for refuting the president-elect’s claim that mass voter fraud took place on Election Day.

"@HighonHillcrest: @jeffzeleny what PROOF do u have DonaldTrump did not suffer from millions of FRAUD votes? Journalist? Do your job! @CNN" — Donald J. Trump (@realDonaldTrump) November 29, 2016

It all began Monday, when CNN senior Washington correspondent Jeff Zeleny discredited Trump’s tweet from the previous day that claimed he won the popular vote “if you deduct the millions of people who voted illegally.”

In a segment on Anderson Cooper 360, Zeleny pointed out how Trump has yet to back up his claim with evidence, calling Trump’s assertion “blatant and baseless.” Zeleny also said the president-elect was being a “sore winner.”

Trump responded on Twitter last night with a combo of his original tweets and quoted tweets of other users, occasionally adding his own comments and erasing the original negative retweets before replying.

"@JoeBowman12: @jeffzeleny just another generic CNN part time wannabe journalist !" @CNN still doesn't get it. They will never learn! — Donald J. Trump (@realDonaldTrump) November 29, 2016

Trump also managed to retweet a self-identifying 16-year-old supporter who goes by @Filibuster.

"@FiIibuster: @jeffzeleny Pathetic – you have no sufficient evidence that Donald Trump did not suffer from voter fraud, shame! Bad reporter. — Donald J. Trump (@realDonaldTrump) November 29, 2016

Zeleny took the criticism in stride and tweeted at Trump that, as a journalist, he’s open to any information the president-elect has.

Good evening! Have been looking for examples of voter fraud. Please send our way. Full-time journalist here still working. — Jeff Zeleny (@jeffzeleny) November 29, 2016

Around 10pm, Trump seemed to wrap up his rant.

.@CNN is so embarrassed by their total (100%) support of Hillary Clinton, and yet her loss in a landslide, that they don't know what to do. — Donald J. Trump (@realDonaldTrump) November 29, 2016

But alas, he re-opened the discussion in the wee hours of the morning.

I thought that @CNN would get better after they failed so badly in their support of Hillary Clinton however, since election, they are worse! — Donald J. Trump (@realDonaldTrump) November 29, 2016

And that concludes Trump’s latest attempt at holding the press accountable. There’s no telling what the rest of today holds.
