The House Intelligence Committee met behind closed doors Tuesday with John Podesta, Hillary Clinton's 2016 campaign chairman, amid complaints by President

Donald Trump that the Obama administration didn't do enough to counter Russian interference in the U.S. election.

Podesta's email account was hacked, as was the Democratic National Committee's. Many of those emails were then leaked, producing a steady, negative and sometimes embarrassing stream of news about Clinton's campaign. But the Democrats didn't cooperate fully with U.S. investigators.

"The president and the entire administration were dealing with an unprecedented incidence of the weaponization" of Russian cyberactivity, Podesta told reporters after emerging from the hearing room. He said they were dealing with the attacks as best as they could "on behalf of the American people."
