Donald Trump took aim Tuesday at former Fla. Gov. Jeb Bush in a wide-ranging interview in which he also touched on subjects ranging from ISIS to the Iran nuclear deal to whether he could form a working relationship with Russian President Vladimir Putin.

On the same day as he announced his run for president, the 69-year-old told Fox News’ Bill O’Reilly in an exclusive interview that he doesn’t have time for the presidential hopeful and brother of former President George W. Bush.

“I'm not a big fan of Jeb Bush. The last thing we need is another Bush, believe me,” Trump told O’Reilly. Trump also extended his criticism to include all politicians, including Democratic hopeful Hillary Clinton.

“This country, if we have another politician -- that includes Hillary -- if we have another politician, this country is going down.”

In the interview, he promised not to pull any punches against ISIS: “I would hit them so hard, I would find a proper general, find the Patton or MacArthur and I would hit them so hard your head would spin."

The New York real estate mogul and reality TV star also said he feels like he can form a relationship with Russian President Vladimir Putin.

“I would be willing to bet I would have a great relationship with Putin. It’s about leadership,” Trump said. When asked by O’Reilly what he was basing that opinion on, Trump responded: “Based on a feel.”

Meanwhile, on the Iran nuclear deal, Trump said he would do a deal with the Iranians, but not the deal currently being negotiated by the Obama administration. “Personally, I’d put on the sanctions big league. I’d double and triple up the sanctions and make a deal from strength,“ he said.
