The top Democrat on the House Intelligence Committee is calling on Congress to "unite to stop" President Donald Trump if he tries to fire Deputy Attorney General Rod Rosenstein or Special Counsel Robert Mueller.
Christopher Ruddy, a friend of the president's, on Monday first said that Trump had been "weighing" whether to fire Mueller, who was appointed by Rosenstein after Trump fired Federal Bureau of Investigation director James Comey in May.
The Thursday document request came on a day when Trump unloaded on a probe he branded a 'witch hunt'.
Rosenstein prepared a memo for Attorney General Jeff Sessions back in early May, which raised repeated questions about how Comey had handled the Hillary Clinton email investigation - at first, that seemed to be the basis for Comey's firing by the President, until Mr. Trump said a few days later that the Russian Federation investigation was on his mind.
It is not clear, however, if Trump was referring in Friday's tweet to Mueller or Deputy Attorney General Rod Rosenstein, who wrote a letter to Attorney General Jeff Sessions recommending that the president fire Comey. Rosenstein also insisted Mueller's investigation would have the resources it needs.
US President Donald Trump's transition team has been ordered to preserve materials related to ongoing investigations into alleged Russian meddling in the 2016 US election. Still, the snowballing investigation has deeply angered Trump, who denies he has any nefarious ties to Russian Federation.More news: Signs Three-Year Extension
Trump: "Oh, I was going to fire regardless of recommendation". But Rosenstein, too, may ultimately have to hand off oversight of the probe given his own role in Comey's firing.
In a May 9 memo, Rosenstein lambasted then-FBI Director James Comey for his handling of the investigation into Hillary Clinton's private email server.
Trump allies have been questioning whether Mueller can lead an unbiased probe, given that some members of his team have made campaign contributions to Democratic candidates. Coats and Rogers have testified that they were not pressured by the Trump administration.
Trump also attacked the media Friday morning. The attorney general was at a White House meeting when the notification came from Rosenstein, prompting the enraged President to scold the attorney general for the turn of events.
Trump's young presidency has been battered by allegations - under investigation both by Congress and the FBI - that Russian Federation interfered to sway the November election in his favor. Last month, news surfaced that Kushner may have discussed creating a secret communications channel between the Trump transition team and the Kremlin with Kislyak. The transition, a nonprofit structurally separate from the Trump campaign, continues to operate with a small staff.
Feinstein noted that Trump does not actually have the authority to fire Mueller, and that any effort to appoint a replacement for Rosenstein with an eye toward shutting down the investigation would result in a "rude awakening" for the President. The memo asks for preservation of electronic communications and data, telephone logs, audio recordings, videos, calendars and other items.
"I'm growing increasingly concerned that the president will attempt to fire not only Robert Mueller, the special counsel investigating possible obstruction of justice, but also Deputy Attorney General Rosenstein who appointed Mueller".
