WASHINGTON – A twitter feud between 2020 democratic hopeful Senator Kamala Harris and Donald Trump Jr. got jokey Friday night.

"Why is Kamala Harris the only person that laughs at her jokes... always way to long and way too hard?” the President’s son asked. “The most disingenuous person in politics... after Hillary.”

Harris responded: “You wouldn’t know a joke if one raised you.”

Harris has been extremely critical of President Donald Trump and has even recently called on his twitter account to be suspended, saying that "Others have had their accounts suspended for less offensive behavior. And when this kind of abuse is being spewed from the most powerful office in the United States, the stakes are too high to do nothing.”

Recent polls show Harris down to mid-single digits behind front runners former Vice President Joe Biden, and Senators Elizabeth Warren and Bernie Sanders.

Still, the Twitter exchange with Trump Jr. got plenty of attention.
