White House adviser Stephen Miller doubled down on the Trump administration's groundless claims of voter fraud in New Hampshire — and across the nation — during in an interview on ABC's This Week on Sunday. Earlier this week President Trump claimed, with no evidence, that voters from Massachusetts were bused to New Hampshire to vote illegally. A member of the Federal Election Commission called it an "extraordinarily serious and specific charge" and asked Trump to "immediately share his evidence with the public." On This Week, host George Stephanopoulos asked Miller, a senior White House policy adviser, to provide that evidence. In fact, he asked three times. Miller said the show was "not the venue" to supply evidence, but repeated the baseless claim multiple times. He said in part: "I can tell you that this issue of busing voters into New Hampshire is widely known by anyone who's worked in New Hampshire politics. It's very real. It's very serious."
