President Donald Trump’s inauguration and move into the White House has not brought an end to his early-morning tweetstorms.

The President on Wednesday morning published a series of tweets to his personal account announcing that he would order an investigation into voter fraud, including a probe into voting by “those who are illegal.”

I will be asking for a major investigation into VOTER FRAUD, including those registered to vote in two states, those who are illegal and…. — Donald J. Trump (@realDonaldTrump) January 25, 2017

even, those registered to vote who are dead (and many for a long time). Depending on results, we will strengthen up voting procedures! — Donald J. Trump (@realDonaldTrump) January 25, 2017

I will be making my Supreme Court pick on Thursday of next week.Thank you! — Donald J. Trump (@realDonaldTrump) January 25, 2017

Trump’s announcement follows his recent debunked claims that he lost the popular vote due to ballots cast by three to five million “illegals.”

During the daily White House briefing on Tuesday, Press Secretary Sean Spicer struggled to respond to Trump’s claim.

He defended the President’s decision to repeat a claim without any evidence.

“He’s stated his concerns of voter fraud and people voting illegally during the campaign and continues to maintain that belief based on studies and evidence people have brought to him,” Spicer said.

And when asked whether Trump would launch a probe into his own claims, Spicer said “anything is possible.”
