Barack Obama has been open with the public about his past drug use.
The former president admits in his 1995 memoir, "Dreams From My Father," that while he was growing up in in Hawaii, he used marijuana and "maybe a little blow."
Sean Hannity implied on Thursday night that Obama's past drug use may somehow cause the failure of President Trump's second travel ban.
The TV personality alleged on his radio show that the judge who issued a ruling against the ban once did drugs with Obama in Hawaii.
"Maybe he should have recused himself from the case. Just a maybe?" he said. "Were they part of the Choom Gang, smoking pot and hanging out and doing a little bit of weed and maybe even a little blow?"
According to one Obama biography, the Choom Gang was the nickname Obama and some of his pot-smoking friends called themselves. There is no indication that the Hawaiian judge was part of the group.
Hannity was correct in saying they were law school classmates -- they both graduated from Harvard Law School in 1991.
However, Obama is in no way involved with the travel ban lawsuit, so there's no need for a judge to recuse himself from the case even if he did know him.
