House Democrats, who are probing President Trump's taxes and finances, also are working on an event that will bring a Yale psychiatrist to talk about the president's mental state.

Lawmakers are planning to focus on Trump's mental faculties at a Capitol event that will feature Dr. Bandy Lee, a Yale psychiatrist who edited The Dangerous Case of Donald Trump and who has raised public warnings about her diagnosis of the president's 'deteriorating' mental state.

Lee has promoted concerns about Trump's mental capacity in TV appearances and through the book, which features articles by other academics and trained psychitrists.

A change.org petition that said Trump 'manifests a serious mental illness that renders him psychologically incapable of competently discharging the duties of President of the United States' garnered more than 70,000 signatures from mental health professionals.

House Democrats are working on an event focused on President Trump's mental fitness where Yale psychiatrist Dr. Bandy Lee will participate

Lee has met with multiple members of Congress, including Rep. John Yarmuth, a Kentucky Democrat who is helping organize the event.

He told the Washington Examiner it would occur in the coming weeks, and would be in a town hall format that would allow for questions. The event is not a congressional hearing, although it will get the imprimatur of participating lawmakers, who would be invited.

'It's going to be an event where she is going to present her findings, and media will be invited, Yarmuch told the paper.

Dr. Lee has said Trump's condition has been 'visibly deteriorating.'

The focus on Trump's mental condition comes as more than 50 Democrats have said they favor beginning impeachment proceedings of the president, following the release of the Mueller report.

Doubts about Trump's mental stability stoked by his political rivals escalated during the tumultuous beginning of his term, then dissipated after White House physician Dr. Ronny Jackson declared Trump 'has absolutely no cognitive or mental issues.”

Jackson also revealed Trump got a 30 out of 30 on a screen for dementia called the Montreal Cognitive Assessment.

It later emerged that former Deputy Attorney General Rod Rosenstein had once offered to wear a wire and spoke about invoking the 25th Amendment, which sets conditions for removal of a president from office when he is unable to carry out his duties.

Trump himself has rendered his own diagnosis, calling himself an 'extremely stable genius.'

The president exhibited some of his best behavior on a trip to Great Britain, dining with Queen Elizabeth II and mostly avoiding public stumbles during his public events. He did unleash an early morning Twitter storm where he went after entertainer Bette Midler, whom he termed a 'washed-up psycho' after she shared a fabricated quote from Trump.
