Democrats are trolling Donald Trump over his refusal to release his tax returns

The Democratic National Committee is trolling Donald Trump over his refusal to release his tax returns.

The committee on Wednesday launched a new micro website called "taxesbytrump.com," which purports to show the presumptive Republican presidential nominee's tax records. Business Insider viewed the site ahead of its launch.

But whenever users attempt to click on a large red "see returns" box, it zips away from the cursor, a reference to the public's inability to view Trump's actual tax information.

In a statement accompanying the site's release, Mark Paustenbach, the DNC's national press secretary criticized Trump for requesting tax information from charities he vetted while refusing to release his own tax records.

"It's more than ironic that Trump needs to see a group's tax records before supporting their efforts, but is unwilling to show his own tax records before asking the American people to support his own bid for the White House," Paustenbach told Business Insider.

"Donald Trump is the standard bearer for a double standard, and his standard for 'deal-making' has no place in the White House," he added.

Despite repeated calls over the last several months, Trump hasn't yielded to decades of precedent for presidential nominees, citing supposed legal advice to wait until the IRS finishes an audit of his records.

Many high-profile Republicans figures have already called on the presumptive Republican presidential nominee to release his returns, a tradition that lends insight into a candidate's personal finances and tax history.

In an interview promoting his newly released memoir ,"The Long Game," Senate Majority Leader Mitch McConnell pointed out that Trump was the only major candidate in decades who hasn't released his tax returns.

"For the last 30 or 40 years, every candidate for president has released their tax returns, and I think Donald Trump should as well," McConnell told Business Insider on Tuesday.
