Republican presidential nominee Donald Trump took a veiled shot at Democratic opponent Hillary Clinton’s health and stamina during the first presidential debate Monday, saying he had been out in the African-American community while she was at home.

Trump made the remark on the heels of trips to Detroit and Philadelphia in recent weeks, which he cited, adding that Democratic politicians who control the cities have let them down. He then took brief aim at her three-day absence from the campaign trail, which happened after she had a medical episode while attending a memorial commemorating the 15th anniversary of the 9/11 terror attacks.
