Sen. John Glenn and Rep. George Miller rent rooms, but that's about as far as that particular comparison can go.

Glenn, the former astronaut from Ohio who is under consideration for the Democratic vice presidential nomination, says his interests in two hotel management companies brought him income of $287,349 last year.At the other end of the lodging business, Miller, a California Democrat, collected between $5,000 and $15,000 in 1987 from three House colleagues who rented rooms in his townhouse near the Capitol.

These are some of the details contained in 1987 financial disclosure statements filed recently by Glenn, Miller and a handful of other lawmakers who received permission to submit their reports after the May 15 deadline.

Glenn's report, which like others gave most information only in broad dollar ranges, showed that he remained one of the wealthiest members of the Senate, which is frequently called "the millionaires' club."

Listing a myriad of investments, he reported assets of from $7,753,163 to more than $15 million, with liabilities at no more than $865,000. Glenn said his income last year was between $1,280,906 and $2,704,480, including his congressional pay of $87,483 and Marine Corps pension of $16,584.

Miller reported earnings last year of from $122,397 to $132,397, including his official salary, $29,914 in speaking and writing fees and rent from roommates Marty Russo, D-Ill., Charles Schumer, D-N.Y., and Leon Panetta, D-Calif.

Miller's only listed assets were his houses in Washington and Martinez, Calif., worth a combined $200,000 to $500,000. His liabilities, mortgages on the properties, were from $60,000 to $115,000.

Patrick Leahy, the Vermont Democrat who chairs the Senate Agriculture Committee, said he received $39,927 from speaking and writing fees.

Sen. Dan Quayle, R-Ind., reported $49,255 in speaking and writing honoraria in 1987. His free trips, paid for by business groups, took him to the mountain resort of White Sulphur Springs, W.Va.; Sun Valley, Idaho; Ft. Myers, Fla.; Monterey, Calif.; and to Salt Lake City for a charity skiing event.
