U.S. President-elect Donald Trump said in a tweet on Sunday that he won the popular vote in the Nov. 8 election “if you deduct the millions of people who voted illegally”, though he provided no evidence of widespread voter fraud.

The allegation by Trump, who won the required votes in the Electoral College to secure the presidency, comes as Democratic rival Hillary Clinton’s lead in the popular vote over Trump has surpassed 2.0 million votes and is expected to grow to more than 2.5 million as ballots in populous states such as California continue to be tallied.

Clinton’s legal team said on Saturday it had agreed to participate in a recount of Wisconsin votes after the state’s election board approved the effort requested by Green Party candidate Jill Stein, which Trump has called “ridiculous.”

“In addition to winning the Electoral College in a landslide, I won the popular vote if you deduct the millions of people who voted illegally,” the Republican Trump tweeted as reporters waited for him to leave his Mar-a-Lago golf resort in Florida to fly back to his residence in New York City.

The U.S. presidential race is decided by the Electoral College, based on a tally of wins from the state-by-state contests, rather than by the national vote. Trump has surpassed the 270 electoral votes needed to win the White House. The Electoral College results are expected to be finalized on Dec. 19. Trump takes office on Jan. 20.

“It would have been much easier for me to win the so-called popular vote than in the Electoral College in that I would only campaign in 3 or 4 states instead of the 15 states that I visited,” Trump added in follow-up tweets.

Several hours later, Trump tweeted, again without citing evidence: “Serious voter fraud in Virginia, New Hampshire and California – so why isn’t the media reporting on this? Serious bias – big problem!” Clinton won all three states.

A spokesman for Trump did not immediately respond to a request for comment.

His tweets come in response to Hillary Clinton’s campaign agreeing to participate in the recount after Green Party candidate Jill Stein pushed the cause. 

In a tweet on Saturday, Trump had derided the fundraising effort by Stein to launch recounts in Wisconsin, Michigan and Pennsylvania as a “scam” that is “is now being joined by the badly defeated and demoralized Dems.”
