Klobuchar said it was unsurprising that McCain's memorial service on Saturday featured numerous subtle references to the Trump presidency because the late senator was so willing to work with Democrats and "stand up and take on bullies."

She noted that she and McCain worked together on legislation to bring down the cost of prescription drugs, as well as a bill aimed at social media disclosure titled the Honest Ads Act.

Klobuchar expressed optimism that Democrats and Republicans alike will take inspiration from McCain's legacy and being working together more closely.

Dozens of current and former officials from across political parties attended Saturday's memorial service for McCain. Former Presidents Obama and George W. Bush delivered eulogies at the event, while Trump visited his golf course.

Bush, Obama and McCain's daughter Meghan McCain each seemed to take swipes at the Trump White House during their remarks praising the Senate icon.

McCain will be buried Sunday at the U.S. Naval Academy.
