Flooding so-called "sanctuary cities" with undocumented immigrants is apparently just one way the president might further his immigration-reform agenda, ABC News reports. It's "an option on the table," Sarah Sanders said Sunday on This Week. "Certainly this wouldn't be our first choice because ideally we wouldn't be dealing with a massive influx of illegal immigrants coming across the border." The White House press secretary also suggested Congress is incapable of comprehending Trump's tax returns should they get released, per the Daily Beast. Calling it a "dangerous, dangerous road," she said that "I don't think Congress, particularly not this group of congressmen and women, are smart enough to look through the thousands of pages that I would assume that president Trump's taxes will be."
