The delay was first reported Thursday by The Associated Press. 

Harkin had previously said that his measure would see a vote on Thursday, but Mikulski never scheduled it. An email from her staff said the timetable was "under review."

“Senator Harkin worked hard on a bill that meets critical needs with funding for Head Start, NIH, and to ensure the maximum Pell Grant award. He remains hopeful that we can still get on the bill this year," said Harkin spokeswoman Kate Frischmann in a statement.
