Klobuchar slammed Cruz after McConnell's move, saying the Texas Republican was the only remaining hurdle to getting the ambassador nominations confirmed.

"We ask him to remove these holds. He has not voiced any concerns about these individual nominees. He voiced concerns about unrelated policy issues," she said, noting that Cruz hasn't been in the Senate to object to the nominees himself.

The presidential candidate has pledged to block State Department nominees over the Iran nuclear deal.

Klobuchar added on Monday that she and Shaheen are planning to "come to the floor every single day and make the case for these countries."
