If the reports have any validity, what had been a chill in the relationship between President Reagan and retired House speaker Tip O'Neill will become a freeze. The Boston Herald reports that it has the uncorrected galleys of O'Neill's memoirs, written with William Novak. In it are harsh words about the president, and the contention that the administration became involved in the arms-for-hostages mess because of the 1986 Senate elections. "The Republicans were desperate to maintain control of the Senate. If they could deliver the hostages it would be translated into a rush of support for the president and his allies in the Senate who were running for reelection," O'Neill reportedly has written.

Other comments on Reagan that could change before the book is published in September: "I blame the president for allowing. . .selfishness to become respectable . . . It was sinful that Ronald Reagan ever became president. He would have made a hell of a king . . ." O'Neill didn't forget former president Richard Nixon, who, he said, didn't burn the incriminating Watergate tapes "because he was greedy. He wanted to use them to write his memoirs and he expected to make a fortune from them." If that's the kind of material that will be in O'Neill's book, people who said his publisher wasted the estimated million-dollar-plus advance are in for a surprise.

Coffin and the Cause

The Rev. William Sloane Coffin, a longtime peace activist and outspoken Protestant minister, announced yesterday from the pulpit of New York's Riverside Church that he plans to resign to head a new antinuclear group.

Coffin described his decision to leave the church as "heart-wrenching," and said he would stay through the end of the year before leaving to become president of the new group, tentatively named SANE-FREEZE.

Two dozen directors of the Washington-based group -- the result of a merger of the Committee for a Sane Nuclear Policy and the Nuclear Weapons Freeze Campaign -- met Saturday and chose Coffin as their new president.

A spokesman for the new group said it will have about 200,000 dues-paying members immediately. SANE has existed since 1957 and the National Nuclear Weapons Freeze Campaign has organized splinter groups throughout the 1980s.

Out and About

Jimmy Carter's activist daughter Amy may be in trouble again. It is being reported in The Providence Journal that the 19-year-old Brown University sophomore is being kicked out of school for failing to keep up with her course work. Brown officials are not talking. Carter has been involved in anti-CIA and other related political activities, and after a court trial earlier this year, she and fellow defendant Abbie Hoffman were acquitted of trespassing charges. Alison Buckser, a classmate, said Amy has considered leaving Brown, adding that if she were dismissed, it would likely have been because she paid more attention to political causes than her classes ...

It is to be hoped that somebody is working on the script about the true-to-life, bizarre divorce proceedings as "Dynasty" star Joan Collins attempts to rid herself of her fourth husband, former Swedish rock musician Peter Holm. There's a wonderful made-for-television movie in this drama. Holm, who claims to be homeless and insists he needs $80,000 a month to keep body and soul together during the divorce proceedings, has demanded -- and has the court's permission -- to be at a deposition session with Collins and his lawyer. Collins has countered -- and has gotten permission -- to have five bodyguards accompany her to the same session. She also received court permission to have Holm searched for weapons. The court, obviously being fair, has given Holm permission to have Collins searched for weapons. Where this little drama will proceed next is anyone's guess, but undoubtedly there is more to come . . .
