State of Play

One night, a thief fleeing through Georgetown in Washington, D.C., is shot by a man carrying a briefcase. A pizza delivery man who witnesses the incident is also shot by the killer and is left in a coma. The following morning, a young woman is killed by a Washington Metro train in what seems to be suicide. Congressman Stephen Collins (Ben Affleck) is distraught to hear that the woman was Sonia Baker (Maria Thayer), a lead researcher on his staff. Collins, who has military experience, is leading an investigation into PointCorp, a private defense contractor with controversial operations involving mercenaries. Collins tells his former college roommate and old friend Cal McAffrey (Russell Crowe), an investigative reporter, that he had been having an affair with Sonia and that she had sent him a cheerful video message on the morning of her death, which he says is inconsistent and unusual behavior for someone about to commit suicide.
Della Frye (Rachel McAdams), a reporter and blogger with the online division of Cal's newspaper and its editor, Cameron Lynne (Helen Mirren), discover that Sonia's death occurred in one of only three CCTV blind spots in the Metro camera system. Cal believes the shootings are related to Sonia's death and finds a link between the petty thief and a homeless girl who sought out Cal. The girl gives him photographs that the thief, a friend of hers, had stolen from the killer's briefcase. The photos show surveillance images of Sonia talking to a well-dressed man. Della visits the hospital where the pizza delivery man is regaining consciousness. While at his room, she witnesses the pizza delivery man shot dead by an unseen sniper. Later, she reviews CCTV footage and recognizes a man she saw at the hospital.
It is later revealed that PointCorp stands to gain 36.95â¬ billion (over $24.3 billion U.S. in 2009) annually from its mercenary activities in the Middle East and domestically. Cal speaks with Collins, who shares his research findingsâPointCorp is cooperating with other defense contractors to create a monopoly and purchase government surveillance and defense contracts, essentially privatizing United States security from the government. Cal's PointCorp insider returns with the address of someone linked to the suspected assassin. Cal finds the assassin living there and calls the police, who force the man to disappear after he shoots at Cal.
Della, following a close lead, finds the identity of the well-dressed man who was speaking to Sonia in the listed photographs. He is Dominic Foy (Jason Bateman), a PR executive working for a subsidiary of PointCorp. Cal blackmails him into talking about his activities with Sonia and secretly tapes their conversation. The PR executive reveals that Sonia was actually paid to spy on Collins and to seduce him to get information for PointCorp, but she fell in love with Collins and was pregnant with his child when she was killed.
Before Cal's newspaper goes to press, Collins goes on record to present his research into PointCorp. Collins's estranged wife Anne (Robin Wright Penn), whose conversation with Cal seems to imply a past love triangle dating back to their college years, reveals that she knows the amount of money Sonia received from PointCorp, after just hearing Collins's statement to the newspaper. After the couple leaves, Cal realizes that Collins knew already that Sonia was working for PointCorp. Cal wonders what Collins would have done had he known he had been tricked and whether Collins himself is connected with Sonia's assassin. A picture of Collins from his military days, with the assassin in the frame, confirms Cal's hunch. Collins reveals that he had been suspicious of Sonia, and that he hired the assassin to watch her. The assassin is U.S. Army Corporal Robert Bingham (Michael Berresse), whose life Collins had once saved. Collins says that Bingham hated PointCorp more than he did, and that he killed Sonia with no authorization from him.
Cal tells Collins that he has three minutes to leave his office before the police arrive, as he has already contacted them. As he leaves the building, Cal is confronted by Bingham. Officers arrive and shoot Bingham before he opens fire. Cal leaves and goes to his office. There, Cal and Della type up their own story, noting that Collins was secured and arrested.

Question: Who does Cal see in the picture with Collins?
Answer: The assassin.
