WASHINGTON — Expressing concern that prominent think tanks may be covertly trying to push the agendas of foreign government donors, the House of Representatives is considering a rule that would require that their scholars testifying on Capitol Hill disclose any such support — a proposal that won immediate bipartisan endorsement on Wednesday.

Representative Jackie Speier, Democrat of California, who drafted the proposal, said lawmakers had a right to know when a foreign government was financing a scholar’s research, even if the foreign government did not control the scholar’s recommendations.

“The American people have a reasonable expectation that these links will be transparent and allow for no appearance of a conflict of interest,” she told a House Rules subcommittee that has started the process of preparing new guidelines to govern conduct during the next Congress, starting in January.

The proposal came in response to an article in The New York Times this month, which found that at least 64 foreign governments, state-controlled entities or government officials had contributed a minimum of $92 million to a group of 28 major United States-based research organizations in the last four years. The total is certainly more, as only those donations made public by the think tank or foreign government could be counted.
