Mike Pence said Donald Trump was being "serious" when he spoke this week about President Barack Obama being the "founder" of ISIS, saying that the GOP nominee "getting people's attention".

Pence defended Trump's rationale for not releasing his tax returns, promised no surprises in his own and lambasted the Clinton family's wealth in a radio interview Saturday on WABC's "Election Central With Rita Cosby".

Pence says he and his family have not become "more wealthy" during his almost 16 years of public service. "There's been a lot of sacrifices, we're a middle class family, and it's been a tremendous honor to serve as I am as governor of IN, and my years IN the Congress, and we'll look forward to making all that information available".

Clinton says that Trump's refusal to release his tax returns goes against a long trend of transparency.

While Republican officials were still trying to figure out what to make of Trump in April - they had pretty much made up their mind by August.

"I think he's made very clear he's going through an audit at this time and will release the taxes when that audit is completed".

The FBI has said there should be an investigation into the connections, but the Department of Justice has shut that down, and Pence said the matter merits further investigation.

Republican presidential nominee Donald Trump made an unusual foray Saturday night into deep-blue CT, pledging to make "a big play" for the Democratic stronghold.

Pence spokesman Marc Lotter confirmed to CNN on Saturday that Pence plans to release his tax returns before Election Day. "It's time for Trump to stop hiding". Trump, meanwhile, is still refusing to release his tax returns.

When Clinton released her returns Friday - they showed that she and her husband had earned an adjusted gross income of $10.6 million previous year, mostly from books and speeches - Clinton made a point to note that she had paid a third of her income in federal taxes. "Because, he said - as has every major party nominee of both parties since - the American public have a right to see my tax returns".

Kaine and his wife, Anne Holton, who was Virginia's secretary of education until she stepped down last month, reported income of $313,441 for 2015.

"I'm confident the American people are going to easily look past all of the rhetoric about tax cuts for the rich.and embrace the policies that Donald Trump is advocating to get America growing again".
