The last bill Murtha* proposed was a constitutional amendment that would permit prayer in schools.

H.J. RES 21 (February, 2005)

Proposing an amendment to the Constitution of the United States relating to school prayer.

Resolved by the Senate and House of Representatives of the United States of America in Congress assembled (two-thirds of each House concurring therein), That the following article is proposed as an amendment to the Constitution of the United States, which shall be valid to all intents and purposes as part of the Constitution when ratified by the legislatures of three-fourths of the several States within seven years after the date of its submission for ratification:

Article--

`Nothing in this Constitution shall be construed to prohibit individual prayer in public schools or to prohibit school officials from including voluntary prayer in official school ceremonies and meetings. Neither the United States nor any State shall prescribe the content of any such prayer.'
