Contra Foes Lose Filibuster Vote

WASHINGTON — Senate opponents of contra aid lost another battle today but said they would fight on to break a filibuster and compel President Reagan to account for millions of dollars in previous assistance they say has disappeared.

The vote on ending the filibuster was an even 50-50, 10 votes short of the 60 required. The filibuster, led by Sen. Jesse Helms (R-N.C.), is preventing action on legislation to freeze contra spending for six months and to order a full accounting of how previous aid was spent. A first attempt to choke off the filibuster failed Monday on a 46-45 vote. (Story on Page 6.)
