president mike pence has confirmed he testified before a grand jury investigating the attack on the capitol, a potentially major development. i can confirm that i did receive a subpoena for the federal grand jury, and i complied with that subpoena. but under advice of counsel, i can t say much more than that. that was my only appearance before the grand jury. i m not going to comment on what others had to testify or not and what they testified to. he s the highest profile witness known to have testified and signals prosecutors are moving beyond the rioters into looking into the trump administration itself. the new york times and the wall street journal are reporting that a second aide to pence greg jacob testified as well. he countered efforts to persuade pence not to certify the electoral results. let s start with evan perez. quite significant developments here. reporter: absolutely, bianna. this is criminal investigators reaching into the trump white house. we re
