The president of the Brookings Institution resigned Sunday amid a federal investigation into whether he illegally lobbied on behalf of the wealthy Persian Gulf nation of Qatar.
Retired Gen. John Allen wrote in a letter to the think tank that he was leaving with a “heavy heart” but did not offer a direct explanation.
“I know it is best for all concerned in this moment,” Allen’s letter said.
A retired four-star Marine general who led U.S. and NATO forces in Afghanistan, Allen’s announcement came less than a week after The Associated Press was first to report on new court filings that showed the FBI had seized Allen’s electronic data as part of the lobbying probe.
Allen has not been charged with any crimes and, through a spokesman, has denied any wrongdoing.
Brookings, which had put Allen on administrative leave the day after the AP’s initial report, issued a statement thanking Allen for guiding the think tank through the coronavirus pandemic and other contributions. The institution said information about the search for a new president would be forthcoming.
