Trump says N Korea went too far in calling Biden 'rabid dog'

US President Donald Trump issued a rare -- if tepid -- defense of Joe Biden on Sunday, saying Pyongyang's depiction of him as "a rabid dog" who should be "beaten to death" went a bit too far.

"Joe Biden may be Sleepy and Very Slow," Trump tweeted, using his nicknames for the former vice president and potential Democratic presidential candidate, "but he is not a 'rabid dog.' He is actually somewhat better than that."
"Rabid dogs like Biden can hurt lots of people if they are allowed to run about," the KCNA statement said. "They must be beaten to death with a stick."
It was not clear what had provoked Pyongyang's ire. But the angry response came after the Biden campaign released an ad condemning Trump's foreign policy and saying that "dictators and tyrants are praised, our allies pushed aside."
"You should act quickly, get the deal done. See you soon!"
