HYDE, IN CLOSING, DEMANDS SENATE 'CLEANSE OFFICE'
House prosecutors and White House lawyers at Senate impeachment trial of Pres Clinton deliver closing statements; Repr Henry J Hyde concludes case for prosecution by accusing defense of resorting to 'theater of distraction and misdirection;' says prosecution's most formidable opponent has been cynicism regarding politics and politicians; speaks bitterly of indignities he and House prosecutors allegedly have endured; compares his team of prosecutors to Henry V's 'band of brothers' at Agincourt; again expresses strong opposition to censure; says failure to convict will send message that lying under oath, while unpleasant and to be avoided, is not very serious; statements by other House prosecutors noted; chief White House counsel Charles F C Ruff urges senators to focus on voices of 'greater eloquence' than on minutiae of lawyers' arguments by heeding those of framers of Constitution, of American people and of generations to come; concludes by reiterating statement made at outset that Pres Clinton is not guilty of charges brought against him; photo (M)
