President-elect Donald Trump claimed on Sunday that “millions” voted illegally in the national election, scoffing at Hillary Clinton’s nearly 2 million edge in the popular vote and returning to his campaign mantra of a rigged race even as he prepares to enter the White House in less than two months.

Trump and his lieutenants assailed an effort — now joined by Clinton — to recount votes in up to three battleground states, calling the push fraudulent, the work of “crybabies” and, in Trump’s estimation, “sad.”

The president-elect himself launched a Twitter offensive that spanned more than 12 hours on Sunday, casting a shadow over the legitimacy of an election that he actually won.

“I won the popular vote if you deduct the millions of people who voted illegally,” he tweeted in the afternoon before alleging in an evening tweet “serious voter fraud in Virginia, New Hampshire and California.” Trump’s transition team did not respond to questions seeking evidence of the claims.

There’s been indication of widespread vote manipulation, illegal voting or hacking that materially affected the outcome one way or the other.

Trump on Sunday tweeted part of Clinton’s concession speech, when she told supporters they must accept that “Donald Trump is going to be our president,” and snippets from her debate remarks, when she denounced the Republican nominee for refusing to say in advance that he would accept the Election Day verdict.

This came on top of his saying it was a “scam” that Green Party nominee Jill Stein was revisiting the vote count in Wisconsin, Michigan and Pennsylvania. Trump won Wisconsin and Pennsylvania, and as of Wednesday, held a lead of almost 11,000 votes in Michigan, with the results awaiting state certification Monday. His Michigan margin was 0.22 percent of the state’s votes.
