Dubai - A Saudi-funded lobbying campaign involving US military veterans that targeted a new law allowing September 11 victims' families to sue the Middle Eastern country in US courts saw some organisers disclose their activities late or vaguely, stymieing public knowledge of the scale of foreign influence in the campaign.
The chief lobbyist for the Saudi Embassy in Washington said it encouraged its subcontractors to be as transparent as possible. But the campaign and the allegations surrounding it show what can happen when the often-murky world of lobbying intersects with emotive American issues like patriotism, protecting US troops and the memory of September 11.
It also highlights how federal laws governing disclosures of foreign influence in American politics are only as strong as they're enforced.
"If the purpose of the statute is to make a public record about how foreign sovereigns are spending money to influence US policy, it's not clear how the US Justice Department's relatively lax enforcement of the statue furthers that goal," said Stephen Vladeck, a law professor and national security law expert at the University of Texas.
Congress voted overwhelmingly for the law in September, overriding a veto by former US President Barack Obama. The law, known by the acronym Jasta, gives victims' families the right to sue any foreign country found to support a terrorist attack that kills US citizens on American soil.
Its critics warn the law opens US troops, diplomats and contractors to lawsuits that otherwise couldn't be filed under the terms of sovereign immunity, a legal doctrine usually protecting governments and its employees in court.
US President Donald Trump is set to visit to the kingdom later in April.
Lobbying
The veterans' lobbying effort began within a month after the vote. Soon, some 70 new subcontractors would be hired by Qorvis MSLGroup, a Washington-based lobbying and public relations firm that represents Saudi Arabia, according to Justice Department filings.
Veterans who spoke to lawmakers had their flights and accommodation paid for with Saudi money distributed by the subcontractors, according to the filings. Some stayed at the Trump International Hotel in Washington. The Saudi involvement was first reported by The Daily Caller, a conservative website, and later explored by the Saudi-skeptic website 28pages.org.
One lobbyist involved, Jason E Jones of Oregon, Wisconsin, said that all involved clearly were told that Saudi money funded the effort.
But David Casler and brothers Dan and Tim Cord, two other veterans, said their first inkling that Saudi money funded the trip was when Jones told the assembled group in Washington that they should speak for themselves and "not the king of Saudi Arabia". They later spoke out on social media over their concerns.
"It was very evident that they weren't forthcoming; they weren't telling us the whole truth," said Casler, a former US Marine sergeant. "They flat-out lied to us on the first day with the statement: 'This is not paid for by the Saudi Arabian government.'"
A parallel veteran effort involved with Qorvis MSLGroup was run by Scott Wheeler, a resident of Lake Elsinore, California, who runs a political action committee called The National Republican Trust. Wheeler's firm, called the Capitol Media Group, reported receiving $365 000 from the Saudi Embassy in three payments corresponding to visits by veterans to Washington.
'A non-story'
Under federal law, anyone working on behalf of a foreign government is required to register within 10 days of being contracted and before beginning any work. But in Wheeler's case, a lawyer filed his paperwork on March 31 - three trips and months after being contracted.
Wheeler declined to answer any questions about his lobbying work, saying this is "a non-story".
Matt J Lauer, an executive vice president at Qorvis MSLGroup, said his organisation told all its subcontractors to comply with federal lobbying regulations. He said his organisation had a long history of filing full reports with authorities on its foreign agent lobbying activities.
But those Foreign Agents Registration Act's guidelines, first put in place over concerns about Nazi propagandists operating in the US ahead of World War II, require the Justice Department to enforce them.
Between 1966 and 2015, the Justice Department has brought only seven criminal cases involving the act, according to an inspector general report released in September. The report recommended the Justice Department's National Security Division - which oversees registrations - improve its oversight, including making sure filings are made on time.
The Justice Department declined to comment.
