The House Oversight Committee subpoenaed three top Biden administration officials to testify before Congress regarding President Joe Biden‘s mental fitness, accusing White House staff of “running interference” for the president as he deals with “cognitive decline.”

The Oversight Committee sent subpoenas requesting testimony from Ashley Williams, special assistant to the president and deputy director of Oval Office operations; Anthony Bernal, assistant to the president and senior adviser to the first lady; and Annie Tomasini, deputy chief of staff. All three are being called to sit for depositions in July.
