On Thursday, President Trump is expected sign an executive order calling for an investigation into voter fraud.

Donald Trump, as both a president and a candidate, has insisted he would have won the popular vote had it not been for the casting of millions of illegal votes.
On Thursday, he is expected to sign an executive order calling for an investigation into voter fraud, reports The Hill.
White House press secretary Sean Spicer was asked about what the inquiry will entail, but offered little information, noting the details are still in the process of being worked out. 
While it is unknown which departments will be involved or what sort of evidence they’ll be looking for, President Trump has made it clear he feels the investigation is necessary. 
During a Wednesday interview with ABC News, President Trump asserted, “You have people that are registered who are dead, who are illegals, who are in two states. You have people registered in two states. They vote twice. There are millions of votes, in my opinion.”
However, as the New York Times states, "There is no evidence to support the claim, which has been discredited repeatedly by numerous fact-checkers."
Paul Ryan, Speaker of the House, also maintains that there is “no evidence” of voter fraud.
Ryan told reporters about Trump’s claims on Tuesday, “I’ve seen no evidence to that effect, and I’ve made that very, very clear.”
