WASHINGTON (AP) β€” A week ago, President Donald Trump was diagnosed with the coronavirus, spent several days at Walter Reed Medical Center for treatment and evaluation, and has since returned to the White House.

Throughout it all, Trump remained in control. He chose not to invoke the 25th Amendment, which details how presidential power can be transferred, either temporarily or more permanently, in the event a president is unable to do the job.

House Speaker Nancy Pelosi cited the amendment Friday when introducing legislation to establish a commission that would help determine whether future presidents are capable of maintaining power during an illness. She said it wasn't about whether Trump was capable, but rather that his illness had shown the need to strengthen "guardrails in the Constitution to ensure stability and continuity of government in times of crisis."
