SNL's ratings have been through the roof since the election season and now that Trump is President. They are doing so well in fact, that NBC is considering airing a 30 minute "Weekend Update" sometime mid-week this spring.
As President Trump continues to bash the show because of their impersonations of him and his White House staff, celebrities continue to guest appear for more impressions. The latest rumor is that Rosie O'Donnell will join a skit as Trump's main advisor, Steve Bannon.
This coming Saturday, Alec Baldwin will continue his Donald bit while also hosting with musical guest, Ed Sheeran. In this promo, Alec promises the show will be a "big deal!" :)
