If Biden wasn't prepared for Harris, will he be ready for Kim Jong Un, Putin or China?

Former Vice President Joe Biden should have been prepared for Sen. Kamala Harris, D-Calif., to criticize his comments about working with segregationist former senators, according to Rudy Giuliani.

Giuliani, President Trump's personal lawyer, on Monday told Fox News' Laura Ingraham, the host of "The Ingraham Angle," that Biden's failure to be prepared for Harris' onslaught raises questions if he is ready to negotiate with foreign rivals.

"If you are not prepared for Kamala, are you prepared for Kim Jong Un and Putin and the people in China?" Giuliani asked, in response to a clip of Biden's wife, Dr. Jill Biden.In a CNN interview Monday, Dr. Jill Biden told Chris Cuomo her biggest surprise in the campaign occurred during the debate last month.

"I think probably Kamala was a little bit of a surprise," she said.

Giuliani said Trump is not concerned about a potential face-off with the Democratic candidates.
