TORONTO (AP) — Toronto Mayor Rob Ford expects to overcome his “little challenge” with substance abuse and get back to work after a stint in rehab, his brother said Friday.

Even as Ford began his treatment at an undisclosed location, another report of the mayor behaving inappropriately while intoxicated emerged Friday. A report written by City Hall officials said Ford turned up intoxicated at the front security office at City Hall on St. Patrick’s Day and threatened a guard who had reported the mayor for similar behavior two years ago.
