Police arrested 28-year-old Ahmad Khan Rahami Monday in connection with two pipe bomb attacks over the weekend. In the first incident, no one was injured during an explosion at a charity race in New Jersey, but 29 people were injured when another bomb exploded in New York City Saturday night. Following the arrest, the presidential candidates each took a moment to assure voters of their national security qualifications. Hillary Clinton pointed to her tenure as Secretary of State for proof of her ability to identify threats. "I have sat at that table in the Situation Room," Clinton said. "I have contributed to actions that have neutralized our enemies. I know how to do this." Businessman Donald Trump used the opportunity to highlight one of the key platforms of his campaign — immigration reform. "We have seen how failures to screen who is entering the United States puts all of our citizens, everyone in this room, at danger," Trump said. Clinton and Trump will go head to head in their first debate next Monday.
