Nunes has since recused himself from the Russian Federation investigation, which is now being led by Rep. Mike Conaway (R-Texas). The official spoke only on condition that neither he nor his country be identified, because he was not authorized to discuss the matter publicly.
That intelligence, the Times reported on Tuesday, came from Israel, a key U.S. ally.
Former officials said it was not uncommon for presidents to unintentionally say too much in meetings and said that in administrations from both parties, staff members typically established bright lines for their bosses to avoid crossing before such meetings.
Trump fired Flynn on February 13.
"What the president discussed with the foreign minister was wholly appropriate to that conversation and is consistent with the routine sharing of information between the president and any leaders with whom he's engaged", McMaster said at a White House briefing, seeking to play down the sensitivity of the information Trump disclosed.
The visit was fraught with bad optics, and Kislyak's attendance - only confirmed by photos from Russian state media - was especially notable because he has been at the center of numerous Trump administration's controversies involving Russia.
Trump is scheduled to visit Israel next week - a trip the White House officials indicated would still go ahead.
"The White House has got to do something soon to bring itself under control and in order".
Since taking office in January, Trump has careened from controversy to controversy, complaining on the first day about news coverage of his inauguration crowds; charging his predecessor, former President Barack Obama, with wiretapping; and just last week firing the FBI director who was overseeing an investigation into potential ties between Trump's presidential campaign and the Russian government.

Trump suggested on Friday (12 May) that there may have been tapes of conversations he had with Comey. Toledo Democratic Rep. Marcy Kaptur released a statement that said she's "deeply concerned" about Trump's decision "to conduct the affairs of our nation in such a compromising manner".
With indisputable facts in short supply, many Republican lawmakers, like Senator John Cornyn of Texas, were declining to comment.
"The information the president relayed had been provided by a United States partner through an intelligence-sharing arrangement considered so sensitive that details have been withheld from allies and tightly restricted even within the USA government", the report said, citing officials.
The President wasn't even aware of where this information came from - he wasn't even briefed on the source or method of this information either, he added.
Citing a memo written by Mr Comey on a meeting with Mr Trump in the Oval Office, the report claims Mr Trump told the Federal Bureau of Investigation chief Mr Flynn had done nothing wrong. But Comey said he did not say anything to Trump about limiting the investigation, replying simply, "I agree he is a good guy".
The newspaper said Comey was in the Oval Office that day with other national security officials for a terrorism threat briefing.
Trump's dissemination of the intelligence to Russians, two Israeli officials told BuzzFeed News, was "our worst fears confirmed". Trump was talking to Russia's foreign minister and its ambassador to the United States, Sergei Kislyak, whose contact with Michael Flynn led to Flynn's resignation as national security adviser and meeting with Jeff Sessions led to the attorney general's recusal from the probe into any collusion between Russian Federation and the Trump campaign.
Intelligence agencies use the phrase "sources and methods" to describe secrets about how intelligence is gathered.
"Trump's tweets tried to explain away the news, which emerged late Monday, that he had shared sensitive, "code-word" information with the Russian foreign minister and ambassador during a White House meeting last week, a disclosure that intelligence officials warned could jeopardise a crucial intelligence source on the Islamic State", the daily said.
