Berkeley Law professor John Yoo told a California State Bar Court on Tuesday that John Eastman’s theory that a vice president has the authority to reject electoral votes is constitutionally valid.

Yoo, appearing as a key witness for Eastman in his disbarment trial, told the court that while the 12th Amendment “is ambiguous” about the vice president’s electoral-counting role and “there’s no definitive answer,” such authority “is the better reading of the constitutional text.”
