Transcript for Trump, upset about Russia probe, meets with deputy AG and FBI director
And next tonight, president trump's growing pressure on the department of justice, on Twitter, the president demanding an investigation the FBI or doj, in his words, infiltrated his campaign for political purposes. There was a meeting today at the white house with the deputy attorney general in charge of the Mueller investigation, and the president's own recent pick not heading the FBI. So, did the president get what he wants? ABC's chief white house correspondent Jonathan Karl. Reporter: Deputy attorney general rod Rosenstein and FBI director Christopher WRAY arrived at the white house today for a meeting with a president highly agitated about the Russia investigation. "I hereby demand," the president declared, "That the department of justice look into whether or not the fbi/doj infull traited or surveilled the trump campaign for political purposes, and if any such demands or requests were made by people within the Obama administration." He seems to be following through on a threat he made last month on "Fox and friends." You look at the corruption at the top of the FBI, it's a disgrace. And our justice department, which I try and stay away from, but at some point, I won't. Reporter: The president's new demand comes in response to a "New York Times" report the FBI, in late 2016, used an informant to question two trump campaign associates about their contacts with Russians. But there is no evidence the FBI infiltrated the trump campaign. Today, Rosenstein made light of his high profile predicament. Deputy attorney generals are very low profile, tend not to be recognized. Reporter: He has now ordered the justice department's internal watchdog to look into the president's concerns, saying -- "If anyone did infiltrate or surveil participants in a presidential campaign for inappropriate purposes, we need to know about it and take appropriate action." Today, the president received a friendly warning from his ally Chris Christie, cautioning attacks on the investigation could backfire. I've told him many times that there's no way to make an investigation like this shorter, but there's lots of ways to make it longer, and he's executed on a number of those ways to make it longer. So, let's get to Jon Karl, live at the white house tonight. And Jon, how rare is it for a president to make these kinds of demands to his own department justice. And rod Rosenstein, what is he trying to do here? Is he trying to appease the president while trying to give Robert Mueller more time to continue his work? Reporter: Well, David, it puts Rosenstein in quite a bind. This is a highly unusual demand. But this is a deputy attorney general, who, for months, has worked with the very real threat that he could be fired at any time. Jon Karl at the white house, another week covering the president.
