Stephen Colbert started his interview with Sen. Elizabeth Warren (D-Mass.) on Monday's Late Show by commiserating about President Trump, and then he threw her a curveball, noting that Warren and Trump both agree the 2016 Democratic primaries were "rigged." Warren took the opportunity to "clarify" her comments to CNN's Jake Tapper, then more cheerfully turned to the Democratic mini-wave in 2017, and her party's — and her own — chances in 2018, when she's up for re-election.
