Rachel Maddow's "bombshell" about President Donald Trump's tax returns turned out to be a bit of a dud.

On her MSNBC show, Maddow reported on two pages of Trump's 2005 return, showing that he made $153 million in 2005 and paid $36.5 million in income taxes ($38 million in total taxes).

Maddow was slammed for overhyping the underwhelming report, which the Washington Post called a "total nothingburger."

On "America's News HQ" today, Geraldo Rivera said Maddow had her own "Al Capone's vault" moment.

On April 21, 1986, millions of viewers tuned in to "The Mystery of Al Capone’s Vaults," a live excavation hosted by Geraldo that promised to dig deep into the catacombs of the gangster's hotel hideout in Chicago.

"We thought it had bodies in it, guns, gold, cash," Geraldo said. "It turned it was an empty Gilbey's gin bottle and a 1926 stop sign."

"I wanted to bury myself in the hole when I found nothing," he added.

Geraldo pointed out that during the 2016 presidential election, after Trump's leaked "Access Hollywood" tape scandal, he said that he might also have some tapes of Trump.

When he didn't deliver the tapes, Maddow said it was "Al Capone's vault" all over again for Geraldo.

"I submit to you that Rachel Maddow now has the mantle of the 'Al Capone vault,'" Geraldo said.
