Sunday: Mulvaney, Cotton, Speier

The House of Representatives passed its version of a tax overhaul bill on Thursday, marking another milestone in the GOP's quest to get a tax reform bill to the president's desk by the end of the year. The debate now moves to the Senate.

In the Alabama Senate special election, Republican candidate Roy Moore faced additional allegations of inappropriate sexual behavior this week. GOP leaders Mitch McConnell and Paul Ryan urged Moore to withdraw from the race, but the GOP candidate insisted he's staying put. Harassment allegations also landed in the Senate itself this week, as radio host Leann Tweeden accused Sen. Al Franken, D-Minnesota, of unwanted advances in 2006.

Mick Mulvaney, the director of the Office of Management and Budget, will join us this Sunday to talk about the White House's push to settle tax reform by the year's end. What can Mulvaney tell us about some of the specifics in the GOP proposals? And can Republicans hold their slim majority together in the Senate to pass a bill?

Sen. Tom Cotton, R-Ark., a strong supporter of the Trump administration, will help us dive into the political dynamics of the GOP amid the push for tax reform and the Roy Moore controversy in the Alabama special election.  What are the Republican Party's options if Moore wins the election on December 12?  Will he face immediate expulsion?

Rep. Jackie Speier, D-Cal., will also join the program to discuss the fallout from the flood of sexual assault and harassment allegations across the country and the allegations against a Senate candidate and a sitting Senator. How will they influence legislation and attitudes moving forward? We'll ask Speier, an advocate for more rules to combat harassment in Congress, to discuss legislation she proposed earlier this week.

National polls are indicating a major dip in support for former-Judge Roy Moore after the accusations, but can Democrats really win in deep-red Alabama? CBS News correspondent Dean Reynolds will share his reporting from Alabama on the political climate there.

As always, we'll have our expert political panel to break down this week's headlines.
