A coalition of "peace organizations" seeking a cut in U.S. military aid to El Salvador has prepared a 30-second commercial that focuses on the killing of six Jesuit priests and two witnesses by the Salvadoran military last November ...

The TV campaign, due to be launched tomorrow in selected markets, is designed to influence an upcoming vote in the Senate on a bill that would withhold half of U.S. military aid for 1991 ...

But so far the El Salvador Public Information Campaign has been unable to get a Washington TV station to carry the ad ...

According to Campaign spokeswoman Denise Bergez, however, only Channel 7 has so far rejected the ad, which has also been offered to Channels 4, 5 and 9 ...

Bergez says that in addition to Washington, the home states of key undecided senators have been targeted and that so far ABC and FOX affiliates in Maine, ABC and NBC affiliates in Rhode Island and an NBC affiliate in Hartford, Conn., have agreed to air it ...

Carol Powell, program services manager for WJLA here, said yesterday the station rejected the commercial because of a policy that forbids "emotional commercials." In her letter to the Campaign Monday turning it down, she pointed out that under the policy, "we do not air material which is intended to inflame or incite unreasoned public responses rather than reasoned debate" and that the Campaign ad is "intended to elicit an emotional response" ...

Powell says the commercial shows someone writing a check to the Internal Revenue Service as a pool of blood slowly spreads across the check and gunshots are heard in the background, followed by images of people being shot in El Salvador ...

"thirtysomething" star David Clennon narrates the ad ...

This morning at the National Press Club a press conference sponsored by the Campaign will include the Rev. Richard O. Buhler, S.J., executive secretary of Jesuit International and Refugee Ministries; former U.S. ambassador to El Salvador Robert White; Fred Ross, executive director of Neighbor to Neighbor; and Angela Sanbrano, executive director of CISPES (the Committee in Solidarity With the People of El Salvador) ...

Earlier this year, Neighbor to Neighbor, another group opposing El Salvador military aid, circulated a commercial in which a cup of what was purported to be Procter & Gamble's Folgers coffee, grown in El Salvador, seeped blood when it was turned upside down. P&G subsequently withdrew $1 million in advertising from WHDH in Boston after it aired the ad, which was not accepted by any Washington station at the time ...

Monday, Day Three of the Senate Judiciary hearings on the nomination of Judge David H. Souter to the Supreme Court, Channel 26's coverage of the hearings averaged a 0.4 rating and a 2 percent audience share over 7 1/2 hours ... which means the hearings were seen in about 7,000 of the area's 1,749,100 TV homes.

Monday night, by the way, was the First Night of the New Season. And CBS won! ...

The third-place network in recent years won with a 16.8 rating and a 27 share for the night, compared with a 14.7/24 for ABC, a 12.9/21 for NBC and a 3.1/5 for FOX ...

CBS was particularly happy that "Major Dad," moved to 8:30, proved to be just the strong lead-in that "Murphy Brown" has needed, averaging a 17.7/27 as "Murphy" jumped to a very strong 19.6/30 in her season premiere. CBS has long hoped that with the right help Murphy could make the top 20 on a regular basis for the network ...

CBS also saw its "Uncle Buck" improve from the previous week, while NBC's big hope, "Fresh Prince of Bel Air," fell off three share points ...

"The Trials of Rosie O'Neill" at 10 did a 14.8/26, not good enough to beat ABC's Monday Night Football during that hour but a strong draw for the women viewers CBS had previously lacked in the time period ...

The football game, between Denver and Kansas City, averaged a 15.9/28 between 9 and 12:14 a.m. ...
