Former Homeland Security Secretary Jeh Johnson told the House Intelligence Committee Wednesday the Democratic National Committee turned down help from the FBI after its system was hacked — and that he had not known about it for months.

“What are we doing? Are we in there?” Johnson said he asked when he became aware of the intrusion. He said the response he received was that the FBI had spoken to the committee but “they don’t want our help.”

“I should have bought a sleeping bag and camped out at the DNC,” Johnson told the panel about what he would have done differently.

Rep. Trey Gowdy, who is one of three members who has taken the lead on the panel’s widespread Russia investigation, later circled back and said camping out would not have made a difference because the DNC also refused to turn over its servers to law enforcement officials to find the culprit.

Rep. Debbie Wasserman Schultz of Florida, who was the chairwoman of the DNC at the time of the hack, said no one at the FBI contacted her at the time.
