House Intelligence Committee Chairman Devin Nunes, R-Calif., said Monday that President Trump "needs to be careful" with whom in his administration gleans advice.

During an appearance on Fox News, Nunes vented frustration over the delayed release of Russia-related documents after Trump changed his mind last month about ordering their immediate declassification in favor of handing the process over to the DOJ inspector general after meeting with Deputy Attorney General Rod Rosenstein and other officials.

"The president I think is a smart guy, and I think he needs to be careful about who he listens to," Nunes said.

Trump said Monday morning he has no plans to fire Rosenstein, following weeks of speculation about how he would react to a news report that said the deputy attorney general plotted against him.

A New York Times report published last month detailed how Rosenstein talked about secretly recording Trump and invoking the 25th Amendment to the Constitution to oust the president after FBI Director James Comey was fired in May 2017. Rosenstein denied considering such actions, and follow-up reports said he was being sarcastic or joking about the "wire."

Despite the good terms that Trump and Rosenstein appear to be on now, GOP lawmakers are still eager to hear from Rosenstein this week.

"I think he does have to come in this week and answer whether or not he was willing to wear a wire or not and whether or not he was looking at invoking the 25th Amendment," Nunes said after dismissing a removal of Rosenstein before the midterm elections. "Those are key questions that he's going to answer before the Russia task force this week supposedly on Thursday."

Republicans are clamoring to see the Russia-related documents declassified — Nunes in particular has called for it to happen before the midterm elections next month — because they say the documents will show a tainted Russia investigation and bias in the top levels of the DOJ and FBI.

Among them are about 20 pages of the June 2017 application to the FISA court seeking the authority to spy on onetime Trump campaign aide Carter Page, who had suspicious ties to Russia. The FISA documents were released earlier in the summer, but in heavily redacted form.

Rosenstein signed off on an extension of that spy effort and is now the DOJ official overseeing special counsel Robert Mueller's Russia investigation.
