White House counselor Kellyanne Conway is expected to skip a House hearing Monday on whether she violated a law prohibiting administration officials from engaging in political work while on the public payroll, according to two Republican congressional officials.

Conway is the only witness listed for a scheduled hearing of the Oversight and Government Reform Committee titled "Violations of the Hatch Act Under the Trump Administration." The Democratic-controlled panel voted last month to authorize a subpoena for her testimony.

The government's independent Office of Special Counsel said in June that Conway had repeatedly violated the law and should be fired. She refused on Monday to answer questions about whether she would show up for the hearing, but two GOP officials said they don't expect her to testify.
