WASHINGTON — A group of United States Olympians from the Rio Games is set to visit the White House on Thursday. It’s a safe bet that one particular lawmaker will be excluded from the guest list.

That would be Representative Jim Himes, Democrat of Connecticut, a former Harvard rower who last week cast the only vote against a bill that would give most United States Olympic and Paralympic medalists a tax break on their victory bonuses.

The vote on the bill — which was approved by the Senate earlier this year and is expected to be signed into law by President Obama — was 415 to 1.

“A lonely, lonely moment,” Himes said Friday when I spoke with him by telephone.

Contrary to what you might be thinking right now, Himes does not hate sports or love income taxes, and he doesn’t disdain the Olympics in general or medal-winning Olympians in particular. Far from it. In the 1980s, he was the captain of Harvard’s lightweight crew, and he said he even tried, unsuccessfully, to make the United States national team. This summer, he said, he was “caught up in the thrill of our Olympic victories” as much as anybody else.
