Two Groups Planning to Sue Over Federal Eavesdropping

By ERIC LICHTBLAU

WASHINGTON, Jan. 16 - Two leading civil rights groups plan to file lawsuits Tuesday against the Bush administration over its domestic spying program to determine whether the operation was used to monitor 10 defense lawyers, journalists, scholars, political activists and other Americans with ties to the Middle East.

The two lawsuits, which are being filed separately by the American Civil Liberties Union in Federal District Court in Detroit and the Center for Constitutional Rights in Federal District Court in Manhattan, are the first major court challenges to the eavesdropping program.

Both groups are seeking to have the courts order an immediate end to the program, which the groups say is illegal and unconstitutional. The Bush administration has strongly defended the legality and necessity of the surveillance program, and officials said the Justice Department would probably oppose the lawsuits on national security grounds.
