Dem Senate candidate Mark Kelly apologizes for staffer's obscene tweet about cops. AZ must vote Red! Democratic Senate candidate Mark Kelly apologized Thursday for a staffer's tweet calling Chicago officers "worthless f—ing pigs," a statement his Republican rival, Sen. Martha McSally, seized on as proof of anti-police bias in the astronaut's campaign. The Twitter post from T.J. L'Heureux was posted in August, a week before he was hired as deputy press secretary, in response to a video showing Chicago cops seizing open umbrellas from protestors during a violent clash. A city official said later that demonstrators had used the umbrellas to shield their actions from view as they pelted police with frozen water bottles, rocks, and pipes. https://www.foxnews.com/politics/arizona-martha-mc-sally-mark-kelly-campaign-spokesman-called-police-officers-worthless-pigs
