cooperate. we ve had discussions with him about potentially appearing before them, trying to make sure we understand what it is they re asking for. as i always did when i was in service to america, i m happy to cooperate with things that are fair and transparent and deliver good outcomes to the american people. we ve learned the committee has already spoken to treasury secretary steve mnuchin. both pompeo and mnuchin discussed using the 25th amendment to remove trump from office. and trump s former chief of staff, mick mulvaney, testified before the committee just yesterday after he offered to come in voluntarily. suffice it to say the list is growing fast. here s how committee member jamie raskin puts it. it s like a waterfall of truth at this point. when you have more than 1,000 witnesses coming in and telling you what had happened, it s the tiny handful of people who are either lying or refusing to participate who begin to feel very nervous about the situation. acc
