Sen. Tom Carper sent a letter to the Office of Special Counsel requesting a full review of another potential violation of the Hatch Act by an official in the Donald Trump administration.

This time, the request pertains to a tweet shared by Stephanie Grisham, deputy assistant to the president and director of communications for the first lady Melania Trump.

On July 11, Grisham shared a picture of Trump’s campaign rally including a hashtag of the acronym “MAGA,” meaning “Make America Great Again.” The tweet, shared from Grisham’s official White House Twitter account, raises serious concerns that Grisham was promoting a political rally in her official White House capacity — precisely what the Hatch Act is designed to prevent.

Carper has requested multiple reviews of potential Hatch Act violations by the Trump Administration, noting that it has “demonstrated a clear disregard for the Hatch Act.” After a previous request from Carper, OSC found that White House Director of Social Media Dan Scavino Jr. violated the Hatch Act in 2017 by using his official position to oppose the election of Representative Justin Amash. Scavino was advised that future political activity through his official capacity would be considered a “willful and knowing violation of the law.” Carper also wrote to OSC regarding a similar violation involving senior adviser to the president, Jared Kushner.

Since Carper’s initial request, the OSC also concluded that U.S. ambassador to the U.N., Nikki Haley, and senior counselor to the president, Kellyanne Conway, have also violated the Hatch Act.

“Taken together, this is a clear pattern of flouting and abusing the law designed to prohibit government officials from using their office to influence political matters,” said Carper in his latest letter.
