WASHINGTON (AP) — Republican presidential candidate Donald Trump is promising to offer a plan within a month to overhaul the tax system, calling himself “king of the tax code.”trump-2

He’s been hinting at such a plan recently, saying that wealthy Americans should pay more.

In a phone-in interview Friday on MSNBC’s “Morning Joe” show, Trump says, “I know the hedge fund guys. … These guys don’t really build anything. They shuffle papers back and forth.”

Trump says he’ll unveil a plan to simplify the tax code and eliminate some deductions, asserting “nobody knows the tax code better than I do.”

Trump says hedge fund managers are big supporters of Democrat Hillary Rodham Clinton and GOP rival Jeb Bush and adds, “I will have a plan.”

He says hedge fund managers won’t be happy.
