The House Ethics Committee said on Monday that its lengthy investigation had found that former Representative Matt Gaetz, Republican of Florida, President-elect Donald J. Trump’s initial choice for attorney general, had regularly paid women for sex, had sex with an underage girl and used illegal drugs. The report was released weeks after Mr. Gaetz withdrew from consideration to be the nation’s chief law enforcement officer and resigned from Congress, and after years in which he had spawned enemies on both sides of the aisle with his bellicose political style.
