Appearing on NBC's "Today" show, Deputy Press Secretary Sarah Huckabee Sanders calls Rosenstein a person "who sets the gold standard within the legal system".
Later, the president and his advisers said Trump had planned to fire Comey since taking office.
Deputy Press Secretary Sarah Huckabee Sanders is expected to give a press briefing at the White House on Wednesday at 1:30 p.m., a day after President Trump fired FBI Director James Comey. Unless I have them every two weeks and I do it myself, we don't have them.
Trump has complained bitterly about his belief that the Obama administration had secretly tapped his phones. "I think we delivered it by hand and by email and that was - and I get it, but you asked me a question and that's the answer", he said.
But as the response grew more critical, Trump ordered his press staff to get out and defend him.
Trump's threat to scrap pressers came amid a surge in speculation following Trump's surprise dismissal of former FBI Director James Comey.
Stone also said Comey had "become a law onto himself" and argued that likening his ouster to the Nixon era "Saturday Night Massacre" was like comparing "apples and oranges". Spicer said, "I've talked to the president, and he doesn't have anything to add to that". However, she said, "I understand that there have been additional requests".
"I have covered the Federal Bureau of Investigation for more than a decade", Apuzzo wrote, in response to Sanders, on Facebook. Republicans and Democrats alike have voiced concerns over the timing of Trump's decision, given that Comey was leading an investigation into potential ties between the Russian government and members of Trump's presidential campaign team. "But Lavrov called the Obama administration's expulsion of Russian diplomats from the U.S.in retaliation late past year "pitiful" and a "dirty" trick".
Spicer was also on reserve duty last Thursday and Friday. "They're the ones that made the recommendation", he said. Here's what you need to know.
"I know that you all will not let this go until it does", Sanders told reporters.
Those sanctions were not discussed Wednesday, Lavrov said in a press conference at the Russian embassy after the meeting.
As Spicer made his way toward the White House door, the swarm of reporters moved with him, shouting questions along the way: Why is the White House suddenly giving statements after pledging to not do so?
