"Last-minute cancellation
The first group of witnesses was supposed to include former Trump campaign manager Bill Stepien, who prior to that role spent several years as an influential Fox News executive. But the committee said Monday morning that due to a family emergency, Stepien wouldn't appear, pushing back the start time of the hearing until at least 10:30 a.m.ET.
Stepien's planned appearance was not voluntary, as he had been subpoenaed by the committee.
The committee said Stepien's counsel will appear and make a statement on the record."
