Mueller briefed on secret comey memos source says

It appears that you're referring to a news article or report that suggests Robert Mueller, the former Special Counsel, was briefed on secret memos written by James Comey, the former FBI Director.

For those who may not be aware, James Comey was fired by President Donald Trump in May 2017, and shortly after, it was revealed that Comey had written memos detailing his conversations with Trump. These memos were seen as potentially incriminating for Trump, as they suggested that Trump had pressured Comey to drop an investigation into former National Security Adviser Michael Flynn.

The article you're referring to likely suggests that Mueller, who was appointed as Special Counsel in May 2017, was briefed on these secret memos as part of his investigation into Russian interference in the 2016 presidential election and potential collusion with the Trump campaign.

It's worth noting that the contents of these memos have been the subject of much speculation and debate, with some arguing that they provide evidence of Trump's obstruction of justice, while others have disputed their significance.

Would you like me to provide more information on the memos or the Mueller investigation?
