Responding to constituent e-mails about Rep.-elect Keith Ellison's decision to use the Koran at his ceremonial swearing-in, a Virginia congressman is warning that "many more Muslims" will be elected demanding to use the Koran unless immigration is tightened.

Republican Rep. Virgil Goode made the comments in a letter sent to hundreds of constituents about Minnesota's Ellison, the first Muslim elected to Congress.

Goode said the United States needs to totally halt illegal immigration and reduce legal immigration.

Ellison was born in Detroit and converted to Islam in college. He did not immediately return a telephone message left today.

The Council on American-Islamic Relations called on Goode to apologize for the letter.

Goode spokesman Linwood Duncan said no apology is forthcoming.
