'Donald may be suffering from memory issues': Nikki Haley responds to Trump's new attack

Donald Trump's lone GOP rival for the Republican presidential nomination said Friday the former president is suffering from "memory issues."

Nikki Haley was responding to Trump's latest attack, also on Friday, in which he accused his own former U.N. ambassador of supporting ex-president Barack Obama. Trump also said Haley is a "flunky" for Mitt Romney, a former Republican presidential nominee.

"Nikki Haley is a flunky for Mitt 'Pierre Delecto' Romney who is kryptonite for the Republican Party," Trump wrote in a Friday post on his own social media site, Truth Social. "She was also a Barack Hussein Obama supporter as seen here, and is currently receiving money from his supporters!"

The former Republican president also included a video in which Haley mistakenly said "Obama" wants to strengthen our military, instead of Romney, for whom she was stumping at the time. Romney then corrected her.

Haley responded to the attack later the same day, calling into question Trump's memory and his support of Democratic politicians in the past.

"Donald may be suffering from memory issues," Haley wrote Friday. "Has he forgotten that he donated money to... Kamala Harris...Hillary Clinton...Chuck Schumer......?"
