House Oversight Committee Chairman Elijah Cummings begged for the “help” of whistleblowers in the government to spill information on President Trump and his team.

“I want to say to everybody, all of my whistleblowers, we need your help, because the president and his lawyers are blocking all, every bit of information that we need to do our investigation, he has been trying to block us,” Cummings, D-Md., said on CBS’s “Face the Nation” on Sunday.
