help with movie name with similar theme to “edge of tommorrow”

Im looking for a movie I watched a long time ago. It has a similar theme to “edge of tomorrow” with time flashbacks. I remember the time flashing back and the viewers get to see the plot through different perspectives. (each flashback uncovers a different set of perspectives). The movie includes a scene where the protagonist is trying to stop shooting? (I think of a president or something, the scene is reminiscent of the movie “Shooter” where the protagonist tries to stop the president from being shot)

An easy giveaway is that the transitions between perspectives always clearly label the time before the climax/big event.

Plz help lmao ty
