>The synagogue’s former president Michael Eisenberg said that while he was president, he had the Department of Homeland Security come to Tree of Life. Eisenberg told the Post Gazette the agency ran safety drills. Eisenberg added, “We had to step it up as far as security, although there had been no threats. The building isn’t designed for today as far as security purposes.” Eisenberg went on to tell CBS Pittsburgh that a maintenance worker who escaped was able to do so because of the DHS’ work. Eisenberg said, “He was able to get out of the building… because the exit doors were working well. I just can’t tell you how thankful I am just to do that one task that Homeland Security told us to do.”
