More than a dozen Republican lawmakers are now calling on President Trump to release his tax returns, echoing the demand that inspired more than 100,000 people to take to the streets on Saturday, Tax Day.

On Monday, White House Press Secretary Sean Spicer again said Trump did not plan to release his tax returns, saying Trump was under an audit. The IRS says being under an audit does not prevent anyone, including the president, from releasing one’s tax returns, telling ABC, “Nothing prevents individuals from sharing their own tax information.”

Trump is the first U.S. president in more than four decades to refuse to release his tax returns. Taxes are officially due today. We’ll have more on Trump’s taxes and this weekend’s protests after headlines.
