Stranded astronaut says he believes Musk's claims that Biden refused to conduct rescue mission

Wilmore said he trusts Musk, who previously told Fox News' Sean Hannity on Feb. 18 that Biden left the astronauts in space for "political reasons." 

Even so, Wilmore later admitted that he had no first-hand knowledge of any talks that occurred to secure their rescue. 

"We have no information on that, though, whatsoever," Wilmore said. "What was offered, what was not offered, who it was offered to, how that process went. That's information that we simply don't have." 

A spokesperson for Biden did not immediately respond to a request for comment from Fox News Digital. 

SpaceX's Dragon is slated to kick off a rescue mission Wednesday and arrive at a space station to retrieve Wilmore and Williams, according to NASA. 

"The most incompetent president in our history has allowed that to happen to you, but this president won't let that happen," Trump said.
