Office of Special Counsel opens case file on Zinke's 'Make America Great Again' socks

(CNN)The US Office of Special Counsel has opened a case file on whether Interior Secretary Ryan Zinke violated the Hatch Act when he tweeted a photo of himself wearing socks featuring President Donald Trump's "Make America Great Again" campaign slogan.

The internal federal watchdog agency opened the file in response to a complaint from the government watchdog Campaign for Accountability.
"Breaking in new socks on a hike with the governors today," the official @SecretaryZinke account tweeted on June 26 with a photo of Zinke's "Make America Great Again" socks, according to the complaint.
That tweet was later removed from the account and replaced with an apology tweet -- which also no longer appears on the account.
    "Earlier I tweeted a pic of my new socks not realizing it had what could be viewed as a political slogan. I've deleted it and apologize for the mistake. I remain excited about all the incredible policy work POTUS is doing," Zinke wrote in the tweet, according to the complaint, accompanied by the same picture with the "Make America Great Again" text blocked out.
    Office of Special Counsel spokesman Zachary Kurz told CNN on Monday, "I can confirm that OSC received the complaint and has opened a case file. However, I'm unable to comment on or confirm whether an investigation has been opened."
      Office of Special Counsel guidance issued on March 5 about the Hatch Act states, "While on duty or in the workplace, employees may not: wear, display, or distribute items with the slogan 'Make America Great Again' or any other materials from President Trump's 2016 or 2020 campaigns; use hashtags such as #MAGA or #ResistTrump in social media posts or other forums; or display non-official pictures of President Trump."
      The Interior Department did not immediately respond to a request for comment about the Office of Special Counsel case file.
