nancy pelosi insisted it was not a done deal, that the house would, in fact, impeach the president. >> why would the public not think that the house is dead set on a course to impeach the president when all of this is going on right now? >> all of this is a seeking of the truth. it's called an inquiry. and if the president has something that is exculpatory, mr. president, that means, do you have anything that shows you are innocent, then he should, make that known. >> house minority leader kevin mccarthy says one democrat confided in him they were embarrassment at the impeachment probe. jeff van drew is one of two democrats who voted to impose the inquiry. van drew remains skeptical of impeachment. and he told me today there was proof with president nixon and president trump, "i have not seen absolute proof." now, just like legislation, impeachment is about the math. it's about the math, it'shm about the math.. with 431 members of the house, democrats need 216 yeas to impeach.
