Additional details have come out about Lt. Gen H.R. McMaster's pay at the Hudson Institute, where he is the Japan Chair. Here is more from the Washington Post:
The Japanese government has also financed the $250,000 annual salary for retired Army Lt. Gen. H.R. McMaster to work for the Hudson Institute, a Washington-based think tank, records show. McMaster received federal approval to take the job in 2019, a year after he stepped down as Trump’s White House national security adviser.
According to McMaster’s application, the Japanese Foreign Ministry provided a $500,000 grant to the Hudson Institute so he could become the new chair of its Japan program. McMaster also reported that the Japanese government was considering giving the think tank a second $500,000 grant.
That annual salary easily puts McMaster in the top 10 at the think tank in terms of pay, with only a handful of top executives and scholars making more (including the president, COO, senior vice president, and a couple senior fellows).
Here is a 2019 Think Tank Watch piece on the Japanese government's funding of Japan chairs at various think tanks.
