NIA-MALIKA HENDERSON, CNN SENIOR POLITICAL REPORTER: And you saw him, as chairman of the Oversight Committee there. During the Cohen hearings, I think probably that's where people will remember him most recently, really, again, being a voice of clarity, moral authority and real insight in terms of where he thought the country should be, the kinds of questions that the Oversight Committee should have about this administration. He took his role very seriously, as you heard Nancy Pelosi speak there, very somberly. And folks very sad today on the Hill and, of course, in Maryland as well where he served, going back to 1996 in the House, a member of the CBC as well. So a big, big loss for that state and for the country as well.</s>KATE BOLDUAN, CNN ANCHOR: And as we were talking, as Nancy Pelosi was speaking, Barack Obama, Michelle Obama, they just issued a statement about Elijah Cummings' passing. It's worth reading. At one point, they write, "As chairman of the House Oversight Committee, he showed us all not only the importance of checks and balances within our democracy but also the necessity of good people stewarding it. Steely, compassionate, principled, yet open to new perspectives. Chairman Cummings remained steadfast in his pursuit of truth, justice and reconciliation." Guys, thank you for being here. So much more to come still this hour. Thank you so much. Coming up still for us, back to Capitol Hill. Because in the hot seat right now is the E.U. Ambassador Gordon Sondland. He's behind closed doors testifying before House committees. And what he's testifying, he is saying that President Trump explicitly directed him and other diplomats to work through Rudy Giuliani with regard to the foreign policy of the United States. What could it mean for President Trump? Stay with us.
