Clay Lonis

Clay Lonis was a Secret Service agent dispatched to Nurmamet Tuman's house in Cat's Claw

Cat's Claw
Clay Lonis was sent up to Tuman's (who he knew as Marcus Lee) to make sure that President Harry Barnes and Chinese Premier Xu Boxiong were safe during their meeting at the Vanderbilt Complex. He met with Nina Myers when she goes to investigate Tuman. Myers left and Ayman al-Libbi arrived, disguised as a gardener. After al-Libbi killed Tuman, al-Libbi presumably killed Lonis along with the other two agents, but this was never confirmed.
