“If Sanders wanted to make people suspicious, he’s doing exactly the right thing,” Thorndike said. “It’s puzzling.”

At Thursday’s Democratic debate in Brooklyn, Sanders said he hasn’t release his tax returns because his wife, Jane, does the family taxes and “we’ve been a little busy lately” on the campaign trail.

“You’ll get them, yes, yeah,” Sanders told CNN’s Wolf Blitzer Thursday. “I don’t want to get anybody excited. They are very boring tax returns . . . No big money from speeches, no major investments. Unfortunately – unfortunately, I remain one of the poorer members of the United States Senate. And that’s what they will show.”

Clinton, who last year released tax returns covering 2007 to 2014, pounced on Sanders’ remark that he and his wife haven’t had time to release his tax records because of their campaign schedule.

“Well, you know, there are a lot of copy machines around,” she said. “There is a long-standing expectation that everybody running release their tax returns . . . you can go to my website and see eight years of tax returns. And I’ve released 30 years of tax returns. And I think every candidate, including Senator Sanders and Donald Trump, should do the same.”

Meanwhile, President Barack Obama and first lady Michelle Obama released their full 2015 tax returns on Friday, as did Vice President Joe Biden and Jill Biden.
