Bill Clinton's former chief of staff Mack McLarty slammed President Trump for thriving on "chaos" and creating "telenovelas" among White House staff.

"I think now President Trump needs to regroup," McLarty told John Catsimatidis on AM 970's "Cats Roundtable" Sunday radio program when asked about the West Wing personnel overhaul. "This White House really needs to not have these telenovelas. The President kind of thrives on chaos."

McLarty, who served as chief of staff to former President Clinton from 1993-1994, said Trump had not transitioned from campaigning to governing mode as he faced set-backs like the inability of a Republican-controlled Congress to pass comprehensive healthcare reform.

McLarty blamed recently departed chief of staff Reince Priebus' ineffectiveness on Trump not empowering him to succeed, adding that Priebus took heat for House Speaker Paul Ryan's failure to corral GOP lawmakers in his chamber.

But McLarty applauded Priebus' successor, John Kelly, as a serious person who "does not suffer fools easily."

Likening the role of chief of staff to "chief javelin catcher," McLarty said Kelly's first priority should be get "a government in place."

"Frankly, the Trump administration has not done that," McLarty said. "You have got to get your legislative agenda, what you ran on, in place and accomplished."
