Washington (CNN) Senate Judiciary Committee Chairman Chuck Grassley told committee Democrats Monday that he would move forward with two hearings for judicial nominees during the congressional recess despite their objections.

"It's unfair to the nominees, who have already flown to Washington D.C. and made travel arrangements for their families to further delay this hearing," Grassley said in his letter to the committee's top Democrat, California Sen. Dianne Feinstein, pointing to previous postponements for hearings. "And it's unfair to the American people."

"As a result of Democratic delay tactics, there are now 154 current and future judicial vacancies, 63 of which are classified as judicial emergencies," he added. "The judiciary simply cannot afford further obstruction from your side."

The two judicial nomination hearings for the Fourth and Ninth Circuit courts are scheduled for Wednesday and October 24. Congress does not return from recess until after the November 6 midterm elections.

Grassley's decision comes in response to a letter from Democrats on the Senate Judiciary Committee earlier Monday that called for the hearings to be delayed until after recess.
