Wisconsin election officials will meet Monday to approve a timeline for a recount of votes in the Nov. 8 election, which will likely begin Thursday.

The schedule for the recount comes after Green Party presidential candidate Jill Stein requested one. Hillary Clinton’s campaign said it would participate in the recount.

The Wisconsin Elections Commission will have a staff meeting Monday morning to request the commission set up a timeline for a recount for all 72 of the Badger State’s counties, the Milwaukee Journal Sentinel reported.

But President-elect Donald Trump lashed out at the efforts on Twitter, saying he would have won the popular vote if there had not been 3 million illegal votes, despite presenting no evidence to substantiate the claim.

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

Trump again falsely tweeted there was “serious voter fraud” in California, New Hampshire and Virginia, three states he lost, but again provided no evidence to support his claim.

Serious voter fraud in Virginia, New Hampshire and California — so why isn’t the media reporting on this? Serious bias — big problem!
