(CNN) -- Ugandan President Yoweri Museveni signed into law Monday a bill that criminalizes homosexuality.
He had gone back and forth about the controversial bill.
Last month, Museveni said he wouldn't sign the bill, describing homosexuals as "sick" people who needed help, not imprisonment. Then he backtracked this month and said he'd sign it because scientists had determined that there's no gene for homosexuality and that it's merely abnormal behavior.
Then, last week, he said he would seek advice from American scientists before he made any decision.
