NEW YORK (AP) _ ABC postponed its special broadcast set for early Tuesday in which Soviet President Mikhail Gorbachev and Russian President Boris Yeltsin were to take questions from U.S. viewers.

Gorbachev and Yeltsin requested postponement of the live ''ABC News Town Hall'' telecast until the Congress of People's Deputies finishes its current session, ABC News President Roone Arledge said from Moscow.

The two leaders said the congress could conclude as early as Wednesday night, network spokeswoman Sherrie Rollins said.

The program, moderated by Peter Jennings, was to have started at around 12:30 a.m. EDT Tuesday, after Monday night football.

Questions would be asked by people in a studio audience in New York, Philadelphia, Miami, Houston, Chicago and Los Angeles and possibly five other cities, the network has said.
