Who does Bingham call in the end of the film?

It was Affleck, but we were supposed to think it was Jeff Daniels and that Bingham was going to kill Affleck. Fake out.

Glad to see someone else addressed this.

It actually makes no sense as near as I could tell.

I agree with mspatera that that line was intended to throw the audience off the final twist by suggesting that Bingham was calling congressman Fergus.

This is a cheap fake out and it creates a plot hole.

If he didn't call Fergus (Daniels), then who did he call? Ann and Stephen Collins (Wright Penn/Affleck) were on their way home from giving his statement to the Washington Globe. At this point in the film we see they are still traveling in the back of a limo. I may have blinked and missed it, but I do not recall seeing Collins answer his phone.

Also, when Bingham makes the call, we are shown an establishing shot of a stately governmental building, implying that this is where he was calling (I believe it was the building where Collins had his office). But again, Collins was in his car on the way home, not at the office.

What makes this fake out more egregious is that they would not be in the character of Collins to give Bingham the green light to whack McAffrey. He hadn't intended to have killed any of the people that Bingham took out, so why would he now suddenly okay his friend being gunned down in the street.

ALSO, as far as Collins knew at this point was that he just sold his alibi to the newspaper, and he had no idea that after he and his wife left the office, that McAffrey had clued into the deception on Collins' part. At the time of Bingham's suiting up, Collins believed he had gotten away scot free.

Also, if Bingham was going to whack McAffrey then why did he drive to Collins' office? How did he know that he would be there, and why - having previously cautious about loose ends and attracting attention - would he stand in full military regalia with a machine gun outside of a government building.

When Collins arrived at the building in one the previous scenes we saw that there were two armed guards outside the front door. Surely they might be alarmed by the sight of this man?

Also, if he were protecting Collins, would it have been the best idea to gun down McAffrey just outside his office?

I have seen people state that Bingham called McAffrey, not Collins. This could make sense in a Hollywood sort of way, but not really.
