(CNN) – Rudy Giuliani will appear at an event with Mitt Romney on Tuesday to mark the anniversary of the assault on Osama bin Laden, a campaign aide confirmed to CNN.
The death of the former al Qaeda leader is currently a political talking point between the campaigns of the former Massachusetts governor and President Barack Obama, with both sides attempting to capitalize on the one-year anniversary.

Giuliani, the former New York City mayor, announced his support of the presumptive Republican presidential nominee last week after voicing support for Newt Gingrich and criticizing Romney earlier in the 2012 election cycle.
Romney and Giuliani ran against each other in the 2008 GOP primary, during which Giuliani's leadership surrounding the events of 9/11 took center stage.
Tuesday's impending event will be the first public meeting of the two Republicans.
