The press pool was invited to the Oval Office at 11:20 a.m. for "what some had assumed would be a spray of President Trump's meeting with Russian Foreign Minister Sergey Lavrov," according to the pool report.
The president said he met with Kissinger to talk about "about Russia and various other matters."
"We're talking about Syria and I think that we're going to do very well with respect to Syria and things are happening that are really, really, really positive," Trump said, according to the pool report. "We're going to stop the killing and the death."
Trump said it was "an honor" to meet with Kissinger, whom he described as "a friend of mine for a long time."
The firing has been compared to when Nixon forced out Archibald Cox, the special prosecutor charged with investigating the Watergate scandal in 1973. Attorney General Elliot Richardson and his deputy, William Ruckelshaus, handed in their resignations during the so-called "Saturday Night Massacre."
Trump was asked about Comey's firing during the press availability.
"He wasn't doing a good job. Very simple. He was not doing a good job," Trump said.
Trump then was asked whether it affected " your meeting with the Russians today?
Trump responded: "Not at all."
