Comey revealed the existence of the memos after he was sacked by President Donald Trump in May 2017.
TPM independently obtained the full memos and published them shortly after the Associated Press uploaded them.
The memos include details about several interactions in the first few months of the Trump administration.
Details that immediately jump out include Trump's request for Comey's loyalty, his desire to have the information put out to the public that he was not a target of the Russian Federation probe, and Comey's assurances that Andrew McCabe was an "honorable man".
They released a statement after news organizations disclosed the contents of the memos Comey provided to the Justice Department.
Trump fired Comey in May 2017 while Comey was leading the FBI investigation into allegations of Russian interference in the 2016 US presidential election and possible collusion between Trump's campaign and the Russians.
The Justice Department sent the redacted version of the memos on Thursday after three Republican House chairmen - Judiciary Chairman Bob Goodlatte, Oversight Chairman Trey Gowdy and Intelligence Chairman Devin Nunes - demanded last week they be provided to Congress.
Trump "said he was trying to run the country and the cloud of this Russian Federation business was making that hard", Comey wrote in a memo on a conversation they had on March 30, 2017. Comey also wrote about Trump's concern over the "Golden Showers" thing, referencing allegations in the Steele dossier that the Kremlin had kompromat on Trump (i.e. the pee tape). And at least on the surface, they appear to back up Comey's description of what he has said in the past was contained in them.
According to the memo, Trump assured Comey that Flynn was a "good guy" who "hadn't done anything wrong" but that he had to be fired because he had misled vice president Mike Pence.
Eleven days later, Trump again pressed Comey about the issue.
"If it's true that Professor Richman had 4 of the seven memos, then in mild of the truth that 4 of the seven memos the Committee reviewed are categorised, it might seem that a minimum of one memo the previous Federal Bureau of Investigation director gave Professor Richman contained categorised data", the letter continued.
The Justice Department has sent Congress confidential memos written by former FBI Director James Comey.
Comey revealed a year ago that he had written the memos after conversations with President Donald Trump, who later fired him. Lawmakers will be permitted to review unredacted copies Friday in a classified setting on Capitol Hill.
Justice officials had allowed some lawmakers to view the memos but had never provided copies to the House committees.
Trump's Republican allies in the House have "referred" Comey to the Justice Department because they say he should be prosecuted.
