Poll: Two-thirds of voters think Trump should release tax returns
Sixty-seven percent of voters said they think Trump should make his returns public, while 24 percent said he shouldn't.
The poll found support for Trump releasing his tax returns across gender, education, age and racial groups.
However, voters were divided along party lines on the issue. Ninety-one percent of Democrats and 68 percent of independents said that Trump should release his returns, while only 30 percent of Republicans said the same.
Support for Trump releasing his tax returns has remained constant over time, with Quinnipiac polls over the past year consistently finding that about two-thirds of voters want the president to publicly disclose them.
During the 2016 election, Trump became the first presidential nominee in decades to refuse to disclose his tax returns. Democrats, as well as some Republicans, have called for him to do so to follow past precedent and to be more transparent about his finances.
Democrats have continued to make Trump's tax returns an issue since the president has taken office, forcing votes on measures to request the documents from the Treasury Department. During the debate over the tax bill, Democrats expressed concerns about passing legislation to rewrite the code without knowing how Trump might benefit from the measure.
Trump has cited an ongoing IRS audit in refusing to release his returns. However, the IRS has said that nothing prevents a taxpayer from disclosing their own tax information.
Quinnipiac's poll found that 52 percent of voters think that Trump hasn't released his returns because he has something to hide, while 19 percent think that he hasn't done so because he's under audit.
The poll was conducted from Feb. 16-19 and had 1,249 participants. It has a margin of error of plus or minus 3.4 percentage points.
