The nation's capital is focused on the Supreme Court this week, and that includes members of Congress. Wednesday is the third day justices will hear arguments considering the constitutionality of President Obama's health care overhaul.

Comedian Bill Maher's $1 million check to the superPAC supporting President Obama's re-election is the first seven-figure donation to the group since Obama tacitly endorsed the fundraising strategy in early February.
