Welcome back, Mayor Ford. Toronto's Rob Ford returned to office on Monday after nearly two months in rehab for substance abuse. Ford said he was in "compete denial" about his problem. "When I look back on some of the things I have said and some of the things I did when I was using, I am ashamed, embarrassed and humiliated," he told a press conference. "I had become my own worst enemy." Ford faces an October election and dozens of opponents.
