WASHINGTON, June 13 (Xinhua) -- A U.S. government watchdog agency on Thursday recommended that White House counselor Kellyanne Conway be removed from federal service for repeatedly violating a law.

In a statement, the U.S. Office of Special Counsel (OSC) said that Conway violated the Hatch Act "on numerous occasions by disparaging Democratic presidential candidates while speaking in her official capacity during television interviews and on social media."

The Hatch Act is a federal law that prohibits employees in the executive branch of the federal government, except the president, vice-president, and certain designated high-level officials, from engaging in some forms of political activity.

"Given that Ms. Conway is a repeat offender and has shown disregard for the law, OSC recommends that she be removed from federal service," said the watchdog.

It added that it has sent a letter to President Donald Trump, along with a report detailing its findings and conclusion.

White House counsel Pat Cipollone, in a letter, accused OSC's report of making "unfair and unsupported claims against a close adviser to the President" based on "multiple fundamental legal and factual errors."

Conway, 52, was Trump's campaign manager in 2016.

A loyal and fierce defender of the president, she's overseeing White House efforts on reducing deaths by opioids.
