Former Secretary of State Hillary Clinton addressed concerns over her health and took a jab at GOP strategist Karl Rove, during part of a sit down interview that aired Friday night.

“How is your health?” Sawyer asked.

“It’s very good, thank you,” responded Clinton, who many suspect will launch a bid for the White House in 2016.

Sawyer followed up, “How serious was it?”

“It was, you know, it was I think a serious concussion,” Clinton answered.

“But the clot in addition, if the clot had dislodged,” Sawyer said.

“Well, can I tell, you that was a scary point,” Clinton said, noting that “because of the force of the fall” she had “double vision for a short period of time.” and “some dizziness.”

The former Secretary of State, who said she’ll “probably” be on blood thinners for the remainder of her life, then took a jab at Karl Rove, who had raised questions about her health earlier this year.

“What would you like to say to Karl Rove about your Brain?” Sawyer asked.

“I know he was called Bush’s brain in one of the books written about him and I wish him well,” Clinton said.

The entire interview with Clinton is set to air Monday night at 9 p.m. ET on ABC.
