WASHINGTON (CNN) — Based on their latest estimates, congressional officials organizing next week’s presidential inaugural expect 2 million people to brave extra-long security lines in the bitter cold to witness Barack Obama being sworn in as the first African-American U.S. president.  Hopefully, people will be of good temper and willing to go through the lines it will take,” said Sen. Dianne Feinstein, D-California, who chairs the congressional committee organizing inaugural events on Capitol Hill. “Because they are going to have to go through magnetometers and they are going to be wanded. Unfortunately, that’s the nature of the time.”

Forecasts show the high temperature on Inauguration Day will be 30 degrees Fahrenheit (-1 Celsius).
