CT Senator Chris Murphy’s career in the upper chamber of Congress has largely been defined by a horrible act that occurred before he even got there. The mass shooting at Sandy Hook Elementary School occurred on December 14, 2012, weeks before Murphy was sworn in as a senator. It took place within the House district he had represented for the prior four years. And news of it reached him just as he was about to catch a train to New York City for a holiday trip with his kids.
