This week Jon Sopel looks at how a video of Donald Trump bragging about groping women and accusations of sexual assault in a New York Times article have changed the dynamics of the presidential campaign.

As one voter said "100% it matters. I don't want anybody in the White House that is accused of something like that. It's unforgivable and indefensible."

Though the core Trump supporters seem unmovable, there is anguish among Republicans having to choose whether to stand by him or not.

Jon Sopel talks to conservative radio host Charlie Sykes and former Republican congressman Bob Walker. While Anthony Zurcher and Jon discuss the most preposterous, jaw dropping, surprising and embarrassing moments of the week.
