Sen. Thomas R. Carper is requesting a formal review of whether senior White House adviser Kellyanne Conway has again violated the federal law that’s intended “to prevent pernicious political activities.”

In question this time is whether Conway’s public statements, including from the White House lawn, about a potential 2020 foe of President Donald Trump, former Vice President Joseph R. Biden Jr., ran afoul of the Hatch Act — which limits political speech by federal employees, especially while on official time.

“You want to revisit this the way Joe Biden wants to revisit, respectfully, because he doesn’t want to be held to account for his record or lack thereof. And I found his announcement video to be unfortunate, certainly a missed opportunity. But also just very dark and spooky, in that it’s taking us, he doesn’t have a vision for the future,” Carper quoted Conway as having said during an April 27 CNN interview.
