President Barack Obama renominated Bacharach in January, along with numerous others who were blocked by Republicans last year.
Senate Republicans did not require that another hearing be held for Bacharach and the other two nominees on Thursday's agenda, but Grassley still invoked his right to delay the vote.
Sen. Patrick Leahy, D-Vt., chairman of the committee, complained that the posts the nominees were chosen to fill had been vacant for two years.
“We have got to do something better,'' Leahy said, adding that Republicans were delaying “qualified people'' who had already been approved by the committee.
Sen. Tom Coburn, R-Muskogee, who supports Bacharach's nomination, predicted earlier this week that Bacharach would be confirmed by the full Senate within a few weeks and that he would push for a vote on him.
