So I sat down with the BBC transcript and here is the relevant section (45 minutes into the speech):
Let's meet our responsibility to the citizens who sent us here. Let's try common sense. A novel concept.
To do that, we have to recognize that we face more than a deficit of dollars right now. We face a deficit of trust - deep and corrosive doubts about how Washington works that have been growing for years. To close that credibility gap we have to take action on both ends of Pennsylvania Avenue - to end the outsized influence of lobbyists; to do our work openly; to give our people the government they deserve.
That's what I came to Washington to do. That's why - for the first time in history - my administration posts on our White House visitors online. That's why we've excluded lobbyists from policymaking jobs, or seats on federal boards and commissions.
But we can't stop there. It's time to require lobbyists to disclose each contact they make on behalf of a client with my administration or with Congress. It's time to put strict limits on the contributions that lobbyists give to candidates for federal office.
