WATCH: Lindsey Graham rips 'staffer' John Kelly and 'irrational White House' in blistering impromptu interview

A fired up Sen. Lindsey Graham (R-SC) took a shot at White House staff during an impromptu talk with the press after the South Carolina senator interrogated DHS Secretary Kirstjen Nielsen in a televised hearing.

At issue for Graham is what happened in a two hour-span last Thursday when he and Democratic Senator Dick Durbin (IL) thought President Donald Trump had agreed with their bipartisan plan to resolve the immigration issue after it was presented to him last Tuesday.

Graham laid the blame on Trump's staff for blowing up the deal and, when asked if he was talking about Kelly, Graham bluntly stated, "He is a very fine man, but he is on staff."

"When you say something happened between Tuesday and Thursday, do you mean that the president got bad advice from someone on his staff?" Graham was asked.

'Yeah, I think someone on his staff gave him really bad advice between 10:00 and 12:00 on Thursday" Graham replied, saying he wasn't going to blame the turnaround on the president.

Saying Americans deserve better and the immigration stalemate needs to be fixed, Graham added, "What we need in order to do better is a reliable partner at the White House. Somebody like the president who showed up on Tuesday. We cannot do this with people in charge at the White House who have an irrational view of how to fix immigration."
