Ruddy appears to have based his assessment on public comments made by a member of Trump's personal legal team.
On ABC News, Jay Sekulow said he was "not going to speculate" on whether the President might order the firing of Mueller. But Sekulow added that he "can't imagine the issue is going to arise". On PBS, Ruddy said that Trump's consideration of moving to fire Mueller was "pretty clear by what one of his lawyers said on television recently". Trump ally, former House Speaker Newt Gingrich, had earlier tweeted that it was time to "rethink" Mueller's ability to be fair.
CNN reporter Jim Acosta tweeted: "Source close to Trump says the president 'is being advised by many people' NOT to fire special prosecutor Robert Mueller".
Democrat Adam Schiff, a member of the House Intelligence Committee, reacted: "If President fired Bob Mueller, Congress would immediately re-establish independent counsel and appoint Bob Mueller. Don't waste our time." Republican Senator Lindsey Graham said firing Mueller "would be a disaster".
Trump does have the authority to remove the special counsel. Muller was appointed by Deputy Attorney-General Rod Rosenstein, and Trump could order Rosenstein to fire him or he could order that regulations that govern the appointment be repealed and then fire Mueller himself. Such an action, though, would be politically perilous. Former President Richard Nixon's attempt to remove a special prosecutor during his tenure led to the resignations of two top Justice Department officials amid the Watergate scandal.
Rosenstein is in an awkward position. He was scheduled to testify before two congressional hearings today and was likely to face even more pointed questions about the Russia probe and the independence of the Justice Department. Attorney-General Jeff Sessions was also scheduled today to testify before the Senate Intelligence Committee. Sessions has recused himself from the Russian probe, a move that gave Rosenstein the authority to appoint a special counsel.
