Sen. Warren on Trump's trial and why 'women win' elections

Sen. Elizabeth Warren, D-Mass., has been present for the Senate impeachment trial of President Trump and heard Trump’s legal team offer its defense of the charges against him. She is also a 2020 Democratic candidate for president. Warren joins Judy Woodruff to discuss why she views Trump’s actions as akin to bribery and what it means to miss the last few campaign days before the Iowa caucuses.
