“She knows how to ignore all the cheap shots and stay focused on the American people,” McCaskill said of Clinton during an appearance on NBC’s “Meet the Press” on Sunday.

Last week, Republican strategist Karl Rove questioned whether Clinton’s 2012 head injury should play a role in her decision to run for president.

McCaskill called Rove’s questions a “cheap political shot.”

“I think Karl Rove is struggling to be relevant” and “trying to be part of the conversation,” she said.

When asked about her support for President Obama during the 2008 Democratic primary, McCaskill said she had to make a “very tough choice” between “two amazing candidates."

Since that election, Clinton has served as secretary of State, which has “enhanced her resume,” McCaskill said.

“It’s her time, and I’m excited to try to be a part of it.”
