It appears Facebook’s privacy concerns aren’t over as two U.S. lawmakers are asking the FTC to investigate them for their tracking practices. Although Facebook has updated their logout logic to remove the tracking cookie, it appears the issue still caught the government’s attention. From the ComputerWorld article:

Rep. Ed Markey (D-Mass.) and Rep. Joe Barton (R-Tex.) wrote an open letter Wednesday urging FTC Chairman Jon Leibowitz to look into Facebook’s tracking of its users even after they log out of the site.

“As Co-Chairs of the Congressional Bi-Partisan Privacy Caucus, we believe that tracking user behavior without their consent or knowledge raises serious privacy concerns,” wrote Markey and Barton. “When users log out of Facebook, they are under the expectation that Facebook is no longer monitoring their activities. We believe this impression should be the reality.”

Considering that cookies have been used for years to track users’ browsing habits, I wonder why this specific case has caught the government’s attention.
