Donald Trump brought out the ALL CAPS Wednesday to show just how seriously he's taking his unsubstantiated claims of voter fraud in the election that he won.

"I will be mexican guys hidden sex alley videosasking for a major investigation into VOTER FRAUD," he wrote over two tweets, "including those registered to vote in two states, those who are illegal and even those registered to vote who are dead (and many for a long time). Depending on results, we will strengthen up voting procedures."

But there's a glaring problem with his proclaimed crackdown -- his own daughter falls under one of the examples he lists of bad voting behavior: people registered to vote in two states.

Tiffany Trump, who voted in New York City in November's election, is also registered in Pennsylvania where she went to college at the University of Pennsylvania, as HeatStreetreported and other outlets confirmed.

Also outed as two-state registrants Wednesday: White House senior advisor Steve Bannon and Trump cabinet nominee Steve Mnuchin.

In a Sarasota, Florida, Herald-Tribune column, Bannon was discovered to be registered at his Florida home and a New York City home. He voted absentee in New York in the 2016 presidential election, according to the paper.

Trump's Treasury Secretary cabinet pick Mnuchin is also a twofer; he's registered to vote in California and New York, as reported by CNN.

Being registered in two states isn't voter fraud. The fraud only happens if that person votes in both places in the same election.

On social media, users were quick to point out the irony of Trump's own family and staff being involved in the very problem he devoted two whole tweets to.

Looks like it's time for Trump to strengthen up voting procedures right at home and at the office.

UPDATE Jan. 26 1:04 PM PT: Looks like another Trump family member is part of the double-registered club: Ivanka Trump's husband, Jared Kushner.

Trump's son-in-law, Kushner, is registered in his hometown of Livingston, New Jersey, and out of New York City, according to election records.

Trump has named Kushner a senior White House adviser after the Justice Department approved the appointment despite federal nepotism laws.

The Washington Post initially reported the Kushner double registration discovery after Trump reiterated what he said in a tweet Wednesday about voter fraud in a TV interview with ABC's David Muir.

“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're registered in a New York and a New Jersey. They vote twice. There are millions of votes, in my opinion," Trump told the news anchor during a White House interview.

Sounds like Trump is describing his son-in-law perfectly with his New York-New Jersey example.
