Is Michelle Obama now Hillary Clinton’s best weapon against Donald Trump?

In a blistering speech, first lady Michelle Obama attacked Donald Trump for his lewd comments about women, calling the “belief that you can do anything you want to a woman” cruel and frightening, but she never mentioned Trump’s name. Aides say this speech is one the first lady has wanted to deliver and is based largely on her own words. NBC’s Andrea Mitchell reports for TODAY from the White House.
