Betsy DeVos, picked by US President-elect Donald Trump for education secretary, speaks during the USA Thank You Tour on Dec. 9 in Grand Rapids, Mich.

The confirmation hearing for Betsy DeVos, the billionaire philanthropist who is President-elect Donald Trump’s choice for secretary of education, has been delayed for almost a week.

DeVos’ hearing was scheduled for Wednesday, but late on Monday night the Senate Health Education Labor and Pensions Committee announced it had been delayed until Jan. 17, next Tuesday.

The move comes after Democrats had raised concerns about the wealthy philanthropists’ incomplete financial disclosures and unfinished ethics review, as Politico reported last week. The top Democrat on the HELP committee asked for a rescheduled hearing, saying she was concerned about “extensive financial entanglements and potential conflicts of interest,” Politico says.

DeVos submitted her financial disclosures to the Office of Government Ethics last month, but has not yet finalized or signed the paperwork, Politico reported on Friday.
