Why Trump is still beefing with "Da Nang Dick"

Blumenthal’s in-laws and Trump go way back in New York real estate circles. Trump and Blumenthal’s father-in-law, Peter Malkin, were competitors in the Manhattan real estate market and eventually clashed over a deal involving control of the iconic Empire State Building.

Those clashes have intersected with Blumenthal’s status as a Democrat who is among “the most vocal on Trump’s potential legal liability,” said Sen. Chris Murphy (D-Conn.).

“Their families traveled in the same circles,” Murphy said. And Blumenthal “is picking a scab regularly that Trump’s particularly sensitive about. Dick’s on TV a lot talking about the Mueller investigation. He doesn’t pull any punches.”
