Boston mayor targeted by Trump immigration czar

Catch up quick: In a recent interview, Wu restated Boston's decade-old policy of refusing to help the feds deport undocumented immigrants unless criminal warrants have been issued.

• That got a sharp response from Tom Homan, Trump's newly-appointed incoming border czar, who called Wu "not very smart."
• "Either she helps us, or she gets the hell out of the way because we're going to do it," Homan said Monday on conservative TV outlet Newsmax.

Threat level: President-elect Trump confirmed Monday he plans to declare a national emergency and use the military to carry out mass deportations.

• Deporting the estimated 11 million undocumented immigrants living in the country is expected to impact around 20 million U.S. families.
