Sen. Joe Manchin (D-W.Va.) on Tuesday lamented the lack of Senate support for tougher gun laws following a mass shooting in Texas hours earlier but rejected the notion of eliminating the filibuster for the purpose of passing such a bill. Manchin noted that he has three grandchildren similar in age to the victims at Robb Elementary School in Uvalde, Texas, where at least 14 kids and one teacher were shot and killed.
