Comey already knows this information and has known it since last year.. Nunes is trying to alert the targets within the administration. Someone said this was an elaborate ruse to keep Sally Yates who was recently let go from DOJ from testifying before Nunes commitee.

So it seems like they are trying to delay the info from coming out and let the folks affected know what is coming. It's not going to work for very long. The first Republican to call for Nunes recusal came out today.

The Yates thing was confirmed tonight

The Trump administration sought to block former acting attorney general Sally Yates from testifying in the House investigation of possible links between Russian officials and Donald Trump’s campaign, according to letters provided to The Washington Post. ........According to the letters, the Justice Department notified Yates earlier this month that the administration considers her possible testimony — including on the firing of former national security adviser Michael Flynn for his contacts with the Russian ambassador — to be off-limits in a congressional hearing because the topics are covered by attorney-client privilege or the presidential communication privilege.

The White House admitted that Jared met for 30 minutes with Sergey Gorkov, the head of Vnesheconombank (VEB)—a state bank that has been sanctioned by the US.
