Reporters, eager to flip a buck make stories up from thin air. There were rumors floating around in 1972, but many were never proven and that's why those stories never made it as far as an official news agency. Even then, every report must be regarded with caution, because most of what's getting reported from thousands of miles away… is rubbish.
This "rumor" was investigated, and mentioned alone in this one op-ed, and sole intent was meant to smear Fischer. Had there been any truth to such a rumor, it would have made front page news and would've been covered in 200 Associated Press Syndicated publications. Here's just one example, culled from a defamatory article, claiming the "White House denied" the rumors. I believe that may be an isolated fact.
The allegations that Henry Kissinger supposedly intervened in Bobby Fischer's affairs... was flatly denied by the White House and until I see a more credible source, than one of Moscow's sycophant journalists; for instance, the New York Times perhaps, stating the “White House confirmed” Kissinger, “this” or “that,” I have no reason to be anything but skeptical.
I've read false reports on the web, claiming Kissinger called Fischer in New York telling him to get on the airplane which is nonsense.
Readers of this page, saw the reports. Jim Slater, the millionaire sent word to Fischer's lawyer, Paul Marshall, that he would (match the offer made by Australia), raise the prize to $225,000 . . . and by this, many newspaper articles confirm, Fischer THEN agreed to make his appearance in Reykjavik.
Fischer's move had nothing to do with Henry Kissinger.

“The White House has denied that Henry Kissinger intervened with Fischer to get the written apology.”
