Andrew Puzder's hearing was scheduled tentatively for Jan. 17. | Getty Puzder hearing could be delayed until February

The Senate Health, Education, Labor and Pensions Committee may delay its confirmation hearing for labor secretary nominee Andrew Puzder until February, according to an aide to Senate HELP Chairman Lamar Alexander.

"Because of the complicated Senate calendar in January, the hearing may not be until February," the aide said.

Puzder's hearing was scheduled tentatively for Jan. 17, but will now be moved because education secretary nominee Betsy DeVos' hearing has been moved to that date, the aide said.
