Tiffany Trump is registered to vote in New York City and Philadelphia, state election records show, despite claims by President Trump senior adviser Kellyanne Conway that she is not, "Today" reported.
Until Wednesday, Steve Bannon, Trump’s chief strategist, was also registered in both Florida and New York, according to local election officials.
NBC News also confimed that Steven Mnuchin, Secretary of Treasury nominee, is registered to vote in New York City and LA County.
The Washington Post reported that Jared Kushner, President Trump's son-in-law and one of his closest White House advisers, is registered to vote in both New Jersey and New York. White House Press Secretary Sean Spicer is registered both in Virginia and Rhode Island, according to elections officials and voting registration records.
President Trump on Wednesday continued to perpetuate unsubstantiated claims of mass voting irregularities by calling for a "major investigation" into what he described as voter fraud. Trump's examples in his tweets all relate to voter registration issues, not fraudulent votes.
Election law experts told NBC News it was "completely natural" to have people on voter rolls in two states or for some people to remain on the voter rolls after they have died. They stressed this did not equate to actual fraudulent voting.
