Earlier in the day, Trump said he would launch an investigation into voter fraud after telling lawmakers on Monday millions of votes cast by undocumented immigrants had caused him to lose the popular vote in November 8 election.

The author of a study, cited as evidence for voter fraud by White House press secretary Sean Spicer, told US media on Tuesday that he found no evidence of non-citizens voting in the 2016 election.
Trump won the 2016 presidential election but lost the popular vote to his opponent Hillary Clinton by 2.8 million votes.
