"The internal federal watchdog agency opened the file in response to a complaint from the government watchdog Campaign for Accountability."
"The Campaign for Accountability responded to the @SecretaryZinke tweet with a link to a March 5 letter posted by the Office of Special Counsel (OSC), which updated its guidance on the Hatch Act in light of Trump confirming he will run for re-election."
On June 27, 2018, CfA called on the Office of Special Counsel to investigate whether Secretary Ryan Zinke violated the Hatch Act by wearing a pair of socks bearing the likeness of President Trump and his campaign slogan, “Make America Great Again”, while participating in the Western Governors’ Association’s annual meeting.
"Earlier in his tenure as Interior secretary, the Campaign for Accountability, a nonprofit government watchdog group, was among the groups that requested the Interior’s Office of Inspector General look into whether Zinke violated the Hatch Act and conflict-of-interest laws by making the trip."
“We’ve been tracking Zinke and what he’s been doing at the Department of Interior,” says Daniel Stevens, executive director of the nonprofit, nonpartisan Campaign for Accountability. “It led us to look into whether he’s violated any rules or laws.”
"New revelations about Ryan Zinke’s unethical conduct seem to break every day. Whether it’s jetting off on private planes, flying his personal flag over the interior Department’s headquarters, or speaking to foreign hockey players on behalf of a campaign donor, Sec. Zinke doesn’t seem to get out of bed in the morning without running afoul of ethical norms."
On October 11, 2017, Campaign for Accountability called on the Office of Government Ethics to investigate whether Secretary Ryan Zinke violated ethics rules that prohibit federal employees from endorsing private entities. Secretary Zinke’s endorsement appears on the website of a fundraising firm he used for his congressional campaigns.
