President Trump speculated that former Vice President Joe Biden lied to cover up the embarrassment of failing to secure the endorsement of former President Obama.

“How he doesn’t get President Obama to endorse him — there has to be some reason why he’s not endorsing him,” Trump said, in an exclusive interview with the Hill.tv. “He was the vice president. They seem to have gotten along. And how President Obama’s not endorsing him is rather a big secret.”
