Lewis wrote that he was “overwhelmed by sadness” in a separate post following the massacre.

I am overwhelmed by sadness at the murder of 49 souls in Christchurch, New Zealand. There is no room in our society for hate, especially on the basis of religion. I pray for our Muslim brothers and sisters and hope that the world community will come to see love as the better way. — John Lewis (@repjohnlewis) March 15, 2019
