The First 100 Days Radio channel will broadcast the President's own words,
unfiltered by political pundits and partisan commentary. This unique
broadcast will explore every side of the Obama story, from his historic
inaugural address; signing the Lily Ledbetter Fair Pay Act, his first bill
signed into law; his first news conference from February 9; and the G-20
speech he delivered on his first trip overseas, and more.

The "100 Days in 100 Minutes" audio documentary will also premiere on
P.O.T.U.S., SIRIUS channel 110 and XM channel 130, on Wednesday, April 29
starting at 6 pm ET.

SIRIUS XM Radio's P.O.T.U.S., Politics of the United States, channel,
originally created to cover the 2008 Presidential election, bridges the gap
between the politics of the White House and the issues that matter most to
Americans, broadcasting an independent forum for political news and
discussion. SIRIUS XM listeners will hear an unbiased roundup of the major
speeches, news conferences, stories and other events that shape political
discussion throughout the day as well as exclusive shows hosted by Pete
Dominick, Tim Farley and Joe Mathieu.
