Does Congress Always Close for Jewish Holidays?

The holiday schedule for both Houses is decided every January.

For 2008, Representatives get a break for Easter, Passover, Rosh Hashanah, Yom Kippur, and Christmas Day. The Senate operates according to a very similar schedule, except it remains in session for Yom Kippur and, at least in 2008, for Rosh Hashanah.

How many Jews are in Congress?
29 in the House, 13 in Senate.
Nice leverage.
