PA Senators Pat Toomey and Bob Casey have reacted to the shootings over the weekend in very different ways. Toomey proposed a background check bill that he worked on with West Virginia Senator, Joe Manchin, That would greatly expand the use of background checks. The bill has failed twice after being introduced after mass shootings. Senator Bob Casey called for sweeping gun control measures and increasing efforts to combat the rise of White Nationalism in America. Gun control measures include a nation-wide ban on semi-automatic assault weapons and a red flag law for dangerous individuals trying to purchase guns.
