The Republican presidential candidate Donald Trump has said he wants a running mate as "an attack dog".

The Wall Street Journal reported, the 70 year old New York billionaire also talked about his top vice presidential picks which has now come down to a few. The list includes, Indiana Governor Mike Pence, New Jersey Governor Chris Christie, former House Speaker Newt Gingrich along with a couple of other politicians who haven't gotten as much attention.

"The New York businessman has said he wanted a seasoned government leader as a running mate. But in the interview, on the way to events with Pence in Indiana, Trump added a new criterion: He wants an attack dog," Trump said.

"I'm getting attacked from all sides," Trump told the daily in the interview in which he called Christie and Gingrich as "two extraordinary warriors."

He said that, personal chemistry is also important.  "You either have it or you don't. I clearly have it with Chris and Newt," he added.

"I'm not doing this for surprises. I'm not doing this for games," Trump said. "I'm doing this because I want to pick somebody that's going to help me get elected, that's going to be good, but also that can serve," he added
