But the memos were just the latest twist in a week of awful headlines for Trump: from the release of a bestselling book in which Comey labels him "morally unfit," to a courtroom circus featuring his embattled personal lawyer and a porn star who alleges a tryst with Trump.
Trump's legal and personal woes -- and wall-to-wall Comey book interviews -- overshadowed his summit with Japanese Prime Minister Shinzo Abe, at which the president confirmed CIA chief Mike Pompeo had met Kim Jong Un in Pyongyang to lay the groundwork for an upcoming summit with Trump himself.
As the week drew to a close, the flurry of developments on the North Korean front were once again eclipsed by the Comey memos -- which depict Trump pressuring the FBI chief over the probe into his campaign's links to Russia before firing him, and could bolster potential obstruction of justice allegations.
"James Comey Memos just out and show clearly that there was NO COLLUSION and NO OBSTRUCTION. Also, he leaked classified information. WOW! Will the Witch Hunt continue?" Trump tweeted Friday in response to the documents.
"We must prevent future attacks on our democracy, and that's exactly what we're doing today," said Democratic National Committee Chairman Tom Perez.
"If the occupant of the Oval Office won't protect our democracy, Democrats will. "
Personal Lawyer Raided
Trump's legal problems reach back to the beginning of his presidency, but have multiplied.
Two weeks ago FBI agents raided the New York residences and offices of his longtime personal lawyer and fixer Michael Cohen, seizing files that could bare Trump's past business dealings and expose more about his relationships with several women in the 2000s, when he was married.
One of them, the porn actress Stormy Daniels, whom Cohen paid $130,000 to keep quiet about an alleged affair with Trump in 2006, showed up to much publicity at the first hearing over the Cohen raid.
Days later she went on the hit show The View where she said she was threatened not to talk about her Trump affair.
Daniels and Trump are now locked in dueling lawsuits that serve to keep the alleged tryst in the headlines.
Separately, Trump is battling a lawsuit that alleges he is breaking anti-corruption clauses in the US Constitution by profiting from the use of his namesake Washington hotel by foreign dignitaries.
Most ominous of all, Trump is under pressure from Special Counsel Robert Mueller's investigation into links between his campaign and Russia, a probe that is also examining possible obstruction by the president.
In a tweet late on Friday night, Trump wrote: "James Comey illegally leaked classified documents to the press in order to generate a Special Council? Therefore, the Special Council was established based on an illegal act? Really, does everybody know what that means?"
It is not the first time Trump has misspelled the word "counsel."
Trump and the Republicans have sought to undermine Mueller's probe by discrediting him and his team as biased and corrupt.
But Comey's new book, "A Higher Loyalty: Truth, Lies and Leadership," has deflected questions back to the president. Comey likens Trump to a Mafia boss who demands absolute loyalty, and lacks any moral foundation.
"This president is unethical, and untethered to truth and institutional values," he writes.
"His leadership is transactional, ego driven and about personal loyalty."
The book, and the memos released by Congress, add support to allegations Trump wanted to suppress the Russia probe and fired Comey because of it.
Trump Expands Legal Team
The strain on the White House is clear. On Thursday Trump added three new attorneys, including former New York mayor Rudy Giuliani and two white collar criminal defense specialists.
According to Axios, the Trump team is still seeking to add more firepower to the legal team, and is pitching for Emmet Flood, who represented former president Bill Clinton is his fight against impeachment in 1998-99.
While Trump doesn't yet face any personal charges, both Democrats and Republicans in Congress have warned him he could face impeachment if he fires Mueller.
