President Barack Obama criticized Republicans for warming to Russian President Vladimir Putin, saying, "Ronald Reagan would roll over in his grave."
At his annual year-end press conference, he said Republicans are falling victim to efforts by Russia to weaken American democracy.
Obama cited a new survey showing that more than one-third of Republicans view Putin favorably. That is up from just 10 percent in July 2014.
Much of his appearance Friday was dedicated to discussing Russia's involvement in hacks of the Democratic National Committee and top Clinton campaign staffer John Podesta.
