President-elect Donald Trump has received two classified intelligence briefings since his surprise election victory earlier this month, a frequency that is notably lower — at least so far — than that of his predecessors, current and former U.S. officials said.

Gregg Phillips, a board member of the conservative anti-voter fraud group True the Vote, tweeted on Nov. 13 that he had “verified more than three million votes cast by non-citizens.” Phillips, who did not respond to a request for comment on Twitter, has not released any data to back up his claims.
