Even Fox News is immediately correcting Trump's lie about being unable to release his taxes

A Fox News host on Wednesday quickly corrected Donald Trump after the president again claimed that he could not release his tax returns because he was under audit.

"Off to San Antonio we go now," Fox News anchor Bill Hemmer remarked after Trump finished an impromptu press conference on the White House lawn. "The president [spoke for] about nine minutes there. A couple things here, tax returns, [he] will not do it. He [says he] is under audit. Legally, you could -- even if you are under audit -- you could make them public."

Trump has repeatedly claimed that he cannot release his tax returns because of an ongoing IRS audit.

"There is no law, as you know, I got elected last time with the same issue and while I'm under audit, I won't do it. If I'm not under audit, I would do it, I have no problem with it, but while I'm under audit, I would not give my taxes," Trump claimed Wednesday.
