Himes argued with users over whether members of Congress were given special privileges regarding the healthcare law.

The exchange started when Himes lamented that House Republicans held another vote to thwart ObamaCare — this time, on a bill to prevent the Internal Revenue Service from playing a role in the law's operations.

Twitter users quickly attacked him over news that the federal government will be permitted to make an employer contribution to Capitol Hill's healthcare premiums on the new insurance exchanges.

Under ObamaCare, members of Congress and their staffs are required to obtain healthcare coverage on the law's new marketplaces.

A glitch in the law would have stopped the federal government from contributing to those employees' healthcare costs as it does now, leading many to fear a "brain drain" from Capitol Hill.

The problem will be fixed next week in guidance from the Office of Personnel Management, according to a White House official.
