House Speaker Nancy Pelosi slammed Republican leadership on their failure to rebuke Rep. Marjorie Taylor Greene over her past comments. Greene repeatedly indicated support for executing prominent Democratic politicians, including Pelosi, in 2018 and 2019 before being elected to Congress. The House Speaker is also criticizing Greene’s placement on the House Education and Labor Committee after comments surfaced that showed her agreeing with people who said the 2018 Parkland school shooting was a “false flag” operation. Democratic Congresswoman Haley Stevens is a member of that committee and has called for Greene’s removal. She tells Anderson Cooper these types of antics have no place in their committee. Plus, South Carolina has detected the first U.S. cases of the Covid-19 strain first seen in South Africa. Scientists are concerned about this strain because it seems to be more transmissible. Dr. Leana Wen is the former Baltimore Health Commissioner, an emergency room physician and is a CNN Medical Analyst.
