"He knew that Comey was going to be removed prior to him writing his memo", McCaskill told reporters, according to Fox News. "It buys them a little time", said a Republican close to the White House.
The Justice Department on Friday issued a transcript of Rosenstein's remarks.
Comey has now agreed to testify before the senate intelligence committee, sometime after Memorial Day.
Rosenstein also told senators that he was "not aware" of a request Comey made for additional resources for the Russian Federation investigation shortly before his firing.
Comey's highly anticipated testimony, which will be slated after the Memorial Day congressional recess, comes after he was sacked by Trump May 9 amid a mounting investigation into Russian involvement in the 2016 election and possible ties between Trump campaign associates and that country. He said that though he was personally fond of Comey, "I thought it was appropriate to seek a new leader".
A black Texas congressman said Saturday that he's been threatened with lynching by callers infuriated over him seeking impeachment of President Donald Trump.

The Canadians finished 13th, ninth and sixth, respectively, over the last three seasons on the World Series. Speaking afterwards, the head coach said: "I'm very, very pleased with the effort from the boys".
Even though Trump himself suggested ending the probe was his motivation, the White House has changed its justifications for the firing several times. Mr Trump said on national television last week that the Russian investigation, which he says is an attempt by Democrats to save face following an embarrassing electoral defeat, was a consideration in making the decision to can Mr Comey.
The White House did not dispute the account of the meeting, according to the Times.
Rosenstein underscored that the memo he wrote was "not a legal brief" and was "not a statement of reasons to justify a for-cause termination.[and] not a survey of FBI morale or performance" but instead "a candid internal memorandum about the FBI Director's public statements concerning a high-profile criminal investigation". Despite the president's furious reaction, some fellow Republicans welcomed Mueller's appointment and expressed hopes it would restore some composure to a capital plunged in chaos. Former FBI Director Robert Mueller, who served under Presidents George W. Bush and Barack Obama, will lead that investigation.
Deputy Attorney General Rod Rosenstein was returning to the Capitol on Friday for another closed-door session, this time with all members of the House. However, at a combative news conference Thursday, he fell short in trying to resolve questions about investigations into his campaign and his first four months in office.
"It does not deter us", Green said of the threats.
Asked point-blank on Thursday if he'd done anything that might merit prosecution or even impeachment, Trump said no - and then added of the lingering allegations and questions: "I think it's totally ridiculous".
