Here are her personal comments about Bannon from her daily briefing:
Unidentified Speaker
HOW SURPRISED WERE YOU WITH WHAT YOU READ SOME OF THE THINGS ATTRIBUTE IT TO MR. BANNON? DID THAT SURPRISE YOU IN ANY WAY AND IF SO, HOW?
MS. SANDERS
CERTAINLY SURPRISING. I BELIEVE THE PRESIDENT COULD AND WOULD WIN OTHERWISE I WOULD NOT HAVE DEDICATED SO MUCH TIME TO IT. I WORKED IN THE WHITE HOUSE SINCE THE VERY FIRST DAY AND A LOT OF CHARACTERIZATION OF -- THAT I SAW THAT HE [Bannon] WAS PUSHING OUT WAS THE OPPOSITE OF WHAT I SAW TAKE PLACE EVERY DAY I HAD BEEN HERE.

And she is correct. I watched the whole briefing. Bannon is a disgusting traitor. I support Trump and his family.
