Congresswoman Zoe Lofgren introduced a congressional resolution Friday urging President Donald Trump to get a medical and psychiatric examination to determine if he should be removed from office.

Lofgren, a San Jose Democrat, said Vice President Mike Pence and the members of Trump’s Cabinet should use the results of the exam to decide whether to yank him from the Oval Office under a never-before-used constitutional provision.

“President Donald J. Trump has exhibited an alarming pattern of behavior and speech causing concern that a mental disorder may have rendered him unfit and unable to fulfill his Constitutional duties,” Lofgren’s resolution states. It urges the Cabinet to “quickly secure the services of medical and psychiatric professionals to examine the President … to determine whether the President suffers from mental disorder or other injury that impairs his abilities and prevents him from discharging his constitutional duties.”

In a statement, Lofgren’s office questioned whether Trump has “early stage dementia” or whether “the stress of office aggravated a mental illness crippling impulse control.”

“I’m not a psychiatrist or a psychologist,” Lofgren said in an interview Friday. “If it was a physical ailment, you would be getting the advice of doctors. The same thing should be true to take a look at his stability here.”

The 25th Amendment states that the vice president and a majority of the Cabinet can temporarily remove the president from office by declaring him or her “unable to discharge the powers and duties of his office” in a letter to Congress. The vice president would then become the acting president.

If the president objects to his or her removal, the debate goes to Congress. A two-thirds majority vote in both houses of Congress is required to keep the president from returning to office.

Lofgren’s resolution follows calls from her fellow Bay Area Rep. Jackie Speier, D-San Mateo, for Trump to be removed under the 25th Amendment.

The White House did not respond to a request for comment.

Trump has faced a tsunami of criticism and increasingly loud calls for his ouster since his comments about the white nationalist rally in Charlottesville last weekend that left three people dead. Trump equated white nationalist protesters with counter-protesters and suggested that removing statues of Confederate generals could lead to removing statues of George Washington and Thomas Jefferson.

Lofgren said she had been worried about Trump’s stability since long before those comments.

While past presidents have used other provisions of the half-century-old amendment to temporarily cede power to the vice president while undergoing medical procedures, the power has never been used by the vice president and the cabinet to remove a sitting president from office.

It’s exceedingly unlikely that Lofgren’s resolution could pass in the Republican-controlled House — and even if it did, congressional resolutions are nonbinding, unlike bills. Still, the strongly worded resolution goes further than most Democrats in Congress have in questioning Trump’s mental stability.

“The bill probably will not pass, but it will stimulate a conversation,” Lofgren said. She said Trump should accept a mental examination “if he cares about the country.”

Also on Friday, several Democrats introduced a resolution aiming to formally censure Trump for his Charlottesville statements. “Democrats will use every avenue to challenge the repulsiveness of President Trump’s words and actions,” House Minority Leader Nancy Pelosi, D-San Francisco, said in a statement.
