WASHINGTON (WVEC) -- The Director of the U.S. Office of Government Ethics has resigned from his position on Thursday.

Walter M. Shaub will be joining Campaign Legal Center as a senior director in ethics beginning July 19.

Shaub tweeted his letter of resignation.

Campaign Legal Center is a watchdog of public officials and helps shape and advance ethics legislation. Two CLC legislation include Honest Leadership and Open Government created by the Office of Congressional Ethics.

“I have had the honor and privilege of serving the American public at the U.S. Office of Government Ethics under three presidents – George W. Bush, Barack Obama and Donald Trump,” said Shaub. “In working with the current administration, it has become clear to me that we need improvements to the existing ethics program. I look forward to working toward that aim at Campaign Legal Center, as well as working on ethics reforms at all levels of government.”

Shaub was appointed on January 8, 2013 by President Obama as Director of the U.S. Office of Government Ethics.

Prior to being appointed, he held the position of deputy general counsel since 2008.

Many people have been commenting on Shaub's twitter post thanking him for his service.
