Democrats don't have the ability to block any of Trump's nominees on their own, but they can use the Senate's rulebook to drag out debate over a nominee for days.

GOP senators are growingly increasingly frustrated by what they view as stall tactics for uncontroversial nominees, while acknowledging that the administration was initially slow to name picks.

Trump added on Monday that he expects McConnell will "start pushing them very hard. And he can do that, and he wants to do that. He also wants to get the judicial nominations through."

Trump's criticism of Democrats, and Schumer by name, comes after he accused the Senate minority leader of hypocrisy over the Iran deal on Twitter earlier Monday.

Schumer opposed the deal but has warned Trump from backing away from the agreement.

Trump has at times signaled that he is willing to work with Schumer, including his surprise agreement to a government funding deal and opening the door to a deal on undocumented immigrants brought into the country as children.

Trump added on Monday that he wants to "have a relationship [with Democrats]. If we don't, we don't."

"I hope to be able to because I like the concept of bipartisan but right now they are doing nothing but obstructing," he said.
