Donald Trump need only find a mirror to battle his current political opponent before he gets to Hillary Clinton, South Carolina Sen. Lindsey Graham said Thursday.

The former Republican presidential candidate said Trump needs to focus on Clinton’s weaknesses instead of causing trouble with the Republican leadership.


Graham’s comments come after Trump declined to endorse House Speaker Paul Ryan and Arizona Sen. John McCain in their respective primaries, as well New Hampshire Sen. Kelly Ayotte.

“From what I can tell, they don't have a strategy to effectively exploit Hillary Clinton's weaknesses,” Graham said Thursday on CNN. "If you really focused on Hillary Clinton's weaknesses and the Obama economy's weaknesses, you would change these numbers. That means you have to focus on your opponent and your opponent is not John McCain, Kelly Ayotte, Paul Ryan. Your opponent right now, Mr. Trump, is yourself.”

Graham, who reiterated that he isn't voting for Trump or Clinton in November, remarked Trump needs to prove to the American people that he has the judgment and temperament to serve as commander in chief. He expressed serious concerns about Trump’s foreign policy remarks, saying he does not believe Trump understands “who our enemies are and who our friends are and he doesn't understand the Mideast for the complexity that it is.”
