Welcome to Morning Joe. It is Wednesday, November 23rd. This morning we are covering overnight

breaking news from Virginia, where another deadly mass shooting has taken place overnight. This time

at a Walmart. We will go live to the scene in just a moment. It comes on the heels of the deadly mass

shooting in Colorado this weekend. The accused shooter in that attack is now out of the

hospital and in jail, expected to appear virtually for a court hearing this morning. We'll be following

that as well. Also, new developments on Donald Trump's legal woes, the Supreme Court delivering

a victory to House Democrats in the long-running battle over the former president's tax returns
