AP FACT CHECK: Spicer says case closed on Russia. It's not

According to a report published at the end of the Obama administration by the outgoing director of intelligence, James Clapper, no coordination between the Trump campaign and Russia had been established.

FBI Director James Comey said last week: "I have been authorized by the Department of Justice to confirm that the FBI, as part of our counterintelligence mission, is investigating the Russian government's efforts to interfere in the 2016 presidential election and that includes investigating the nature of any links between individuals associated with the Trump campaign and the Russian government and whether there was any coordination between the campaign and Russia's efforts."

Rep. Adam Schiff of California, top Democrat on the House Intelligence Committee and a recipient of classified briefings, has said "there is more than circumstantial evidence now" of a relationship between Russian interests and Trump associates.

A close adviser to Trump, son-in-law Jared Kushner, has agreed to talk to lawmakers about his business dealings with Russians.
