Aaron Schock is a handsome US congressman so fit that he has posed for the cover Men's Health magazine, his shirt unbuttoned and washboard abs on full display.

Schock is a Republican who is against gay marriage and voted against the repeal of the military's Don't Ask Don't Tell policy but it is the 31 year old's physique and sense of  fashion that seems to be fueling speculation about his sexuality.

So at the Republican National Convention this week, gay journalist Michelangelo Signorile asked Schock if he is gay.
