(CNN) President Donald Trump's nominee for an Alabama federal court judgeship is being criticized for not disclosing in his confirmation process his wife's role in the White House.

Brett Talley did not disclose his wife's position as chief of staff for White House Counsel Donald McGahn on his Senate questionnaire, according to The New York Times.

Sen. Dianne Feinstein, the top Democrat on the Senate judiciary committee, said the full Senate should not consider Talley's nomination until he explains why he failed to disclose the potential conflict of interest.

"By failing to disclose that his wife is one of President Trump's lawyers," Feinstein said in a statement, "Talley has betrayed his obligation to be open and transparent with the Senate and American people."

The Senate judiciary committee advanced Talley's nomination along a party-line vote Thursday and a full Senate vote is expected soon.
