While other area government officials pleaded for getting on with the job of building Metro with cuts if necessary, Montgomery County Executive James P. Gleason yesterday reiterated his opposition to anything less than a White House commitment to fund the entire 100 mile system.

Speaking at the annual meeting of the Metropolitan Washington Board of Trade, Gleason declared, "Someday I might get credit for doing this."

The Montgomery County chief is holding back $15 million in local funds - and action which in turn holds back $100 million in federal and state funds - in an effort to assure construction of the Glenmont line beyond Silver Spring.

He lamented what he called the Carter administration's lack of a transportation policy and accused Transportation Secretary, Brook Adams of just carrying out the objectives of the Office of Management and Budget. He called on congressional leaders to demand a full 100-mile commitment for Adams.

D.C. City Council Chairman Sterling Chairman Sterling Tucker told the audience: "All routes should be completed. But our minds are still open. Six to 10 miles may not be built eventually." He again emphasized the need for an area-wide transportation tax.

On the subject of rent control, Prince George's County Executive Winfield M. Kelly supported the expiration due at the end of this month, saying control had a deleferious effect on encouraging investment in housing. "Any community that stays in rent control winds up in a worse housing situation than when it went in he said".

By contrast, D.C. Corporation Counsel John Risher, speaking for the absent Mayor Walter Washington, advocated continued rent control. However he called for creation of an independent agency, free of political influence, to handle rent control.

Referring to a proposed D.C. convention center, Del. Walter Fauntroy (D-D.C.) declared, "I wouldn't close the book on it. (Rep. William H.) Natcher, (head of the House District appropriations subcommittee) hasn't given up. And I haven't."

Outgoing Board of Trade president, relator Foster Shannon, got a hand from the audience when he attacked "the all too popular notion that it's a sin to make a profit." He added, "Economic development will only take place where the opportunity for profits exists." He will be succeeded Jan. 1 by R. Robert Linowes, a partner in the law firm of Linowes & Blocner.
