Transcript for Nancy Pelosi calls for Secretary of Labor to 'step down'
Washington fallout as well so let's bring in Mary Bruce. Mary, the question now focuses on Alexander Acosta. He is the labor secretary right now. He was the U.S. Attorney in charge down in Miami when this plea deal was struck and that's why Nancy Pelosi is calling for him to resign. Reporter: Yeah, George, in a rare move the speaker is saying Acosta has to go. Pelosi tweeting overnight he must step down saying he engaged in an unconscionable agreement with Jeffrey Epstein kept secret from your roijs young victims preventing them from seeking justice saying it was known by the president when he appointed him to the cabinet. Here on the hill there are mounts questions from Democrats about how Acosta handled this prior case that will he had to that minimal sentence but so far they have not summoned Acosta here to the hill to testify on this matter. We will see if that comes. On another front the administration's case against Obamacare, big court hearing today. Reporter: This is a big day for the fate of Obamacare. In New Orleans today 18 republican-led state also make their case before an appeals court asking them to strike down Obamacare. We won't know any ruling until September. Just oral argue manies but the practical and political implications could be tremendous. If the law is struck down, well then that could wipe out coverage for millions of Americans, protections for people with pre-existing conditions, coverage for young adults who stay on their parents' plans could be wiped out as well as greater access through the expansion of medicaid, all of this could be in jeopardy but, George, even if Republicans do win in the courts they could lose big politically because as the president recently told you last month that his health care plan is coming sometime soon, George, right now Republicans do not have a plan to replace Obamacare. It will be front and center, 2020 campaign, thanks very much.
