WASHINGTON (AP) — Russian President Vladimir Putin is accusing the Obama administration of trying to undermine President-elect Donald Trump by spreading fake allegations.

Putin, speaking at a news conference in Moscow Tuesday, described a dossier on Trump as part of efforts by the Obama administration to “undermine the legitimacy of the president-elect” despite his “convincing” victory.

Putin dismissed as “fake” the dossier’s unverified allegations about Trump’s sexual activities at a Moscow hotel. He added that people who ordered it are “worse than prostitutes.”

Trump has rejected the allegations as “fake news” and “phony stuff.”
