President Trump abruptly cancels a planned peace summit with the Taliban. His idea to invite the Al Qaeda allies to Camp David on the week of 9/11 causes a split in the administration -- and alarms key Conservatives in Congress. Plus, Congress is back from its summer break. Republicans want to know if the President is serious about new gun control legislation. Democrats are trying to balance a family debate about whether to stick to issues like guns and health care or move ahead with investigations and impeachment. And remember Valerie Plame? The ex-spy is now running for Congress -- and putting her CIA driving lessons to use in a new campaign video. Today's Panel: CNN's Abby Phillip, Carl Hulse with The New York Times, Matt Viser with The Washington Post and Jackie Kucinich with The Daily Beast.
