Story highlights Mike Pence says he'll release his tax returns before Election Day

That's in contrast to GOP nominee Donald Trump, who refuses to do so

(CNN) Donald Trump's running mate, Mike Pence, said Saturday he plans to release his tax returns before Election Day, even as the GOP nominee has continued to resist calls to release his own tax returns.

"When my tax returns are released, it's going to be a quick read," Pence said Saturday in an interview on WABC Radio, adding that he is also in the process of completing his financial disclosure forms as required under federal law.

Pence spokesman Marc Lotter confirmed to CNN on Saturday that Pence plans to release his tax returns before Election Day.

"He said in that interview that it would happen before the election," Lotter said when asked for a timeline on the release of Pence's tax returns.

Pence's decision comes one day after Hillary Clinton, the Democratic presidential nominee, and her running mate Tim Kaine released their tax returns to the public.
