President-elect Obama will hold today his fifth press conference in as many days. Rep. Ray LaHood (R-Ill.) is expected to be announced Transportation Secretary at the 1:15 p.m. CT event in Chicago.

Possibly joining LaHood at the event is former Dallas Mayor Ron Kirk, who is reportedly Obama's choice for Trade Representative, and Rep. Hilda Solis (D-Calif.), tapped for Labor Secretary.

Obama already announced this week his energy and environment team; the secretaries of Education, Agriculture and Interior; as well as the chair of the Securities and Exchange Commission.
