BOLDUAN: It appeared that the new NAFTA trade deal, USMCA, was a done deal. In fact, the House is supposed to be voting on it days from now. But it just hit a snag not from Congress but from one of the partners in the deal. CNN's Matt Rivers is in Mexico City with more on this. Matt, what are you hearing?</s>MATT RIVERS, CNN INTERNATIONAL CORRESPONDENT: Kate, basically, Mexico is balking at provisions that were added a bill that was just introduced last Friday. As a part of this negotiation, Democrats have long wanted to make sure that enforcement measures were added to new Mexican labor laws that were enacted here in Mexico as part of this deal. Democrats wanted inspectors from the U.S. on the ground here in Mexico making sure new labor laws were being followed. Now Mexico's government is saying, hold on, we didn't agree with that, nobody told us that, and we would view any inspectors from the U.S. on the ground here in Mexico as a violation of our sovereignty. Even though Mexican Senate passed this bill last week, on Thursday, they're now saying, hold on, we're not on board. There are negotiations going on between Mexican negotiators and American negotiators today in Washington. We'll wait and see what comes out of this meeting. But this deal just got more complicated.</s>BOLDUAN: Complicated. Done deal, not a done deal. It's still up in the air at this point. Good to see you, Matt. Thank you so much. I really appreciate it. So coming up, still ahead, as the House prepares to vote on impeachment, a top Democrat in the Senate lays out his opening bid for what he wants to see and not see in the Senate trial.
