"According to The Washington Post, Democrats have introduced more than 30 pieces of legislation aimed at combatting gun violence in the past year. Only four have had GOP sponsors. While some GOP senators have expressed an interest in fixing some gaps in existing law, it has been President Trump and other Republicans who have launched several efforts to loosen gun-control laws."
