So far, the previous releases have fleshed out details that Mueller summarized in his final report regarding President Donald Trump's and his campaign's actions. The memos so far have revealed, for instance, how top Trump campaign officials witnessed the President and other Trump campaign officials pushing for the release of stolen Democratic emails and supported a conspiracy theory that Ukraine hacked the Democrats in 2016.

The memos, called 302s by the FBI, were typed up by agents or prosecutors after they questioned each witness. The Justice Department has kept many of the memos heavily redacted as they continue to release them this year.

This is a breaking story and will be updated.
