Senate Minority Leader Robert Dole says the Senate should "stop the dragnet" for information about defense secretary-designate John Tower and move ahead with his confirmation. Dole, a Kansas Republican, said he has seen nothing to disqualify Tower for the post. "I think we should stop checking every rumor. Unless there's some criminal activity, let's get on with the vote," Dole said on the CBS-TV program "Face the Nation." Senate Majority Leader George Mitchell, D-Maine, another guest on the program, promised a quick vote on the Tower nomination once it leaves the Senate Armed Services Committee. But Mitchell, who said he had not read the FBI reports on Tower, said allegations surrounding Tower's private life are "an appropriate subject of inquiry" because of the importance of the defense post.
