Marco Rubio opposition researcher Joe Pounder taunted Sarah Palin on Monday after she cancelled her speech for Donald Trump — but before the reason was made public.

Palin canceled because her husband Todd was hospitalized in a “bad snow machine accident.”

“@realdonaldtrump surrogate operation not really working” Pounder said in response to Palin’s cancellation.

Pounder has not offered a follow-up tweet apologizing for his remarks as of this writing.

Palin was supposed to appear at a Trump rally in the Villages in Florida, but could not make it due to Todd’s accident. She later made it to a Trump event in Tampa and then returned to tend to her husband.

Pounder has been responsible for running a full-fledged attack on Trump from his perch at the Rubio campaign. As Breitbart News reported, the Rubio camp launched seven coordinated last-minute attacks on Trump before Super Tuesday. The attacks did not work well, as Rubio continued to decline in the delegate race.

The Rubio campaign did not immediately return a request for comment for this report on Pounder’s remarks.
