House Minority Leader Nancy Pelosi D-Calif., said Thursday that obtaining President Trump’s tax returns as part of an investigation into possible tax evasion or other lawbreaking will be “challenging.”

“I think it’s a little more challenging than you might think,” Pelosi told reporters Thursday. “Yes, there is popular demand for the Congress to request the president’s tax returns,” but, “I’m sure that the White House will resist and the question is, where do we go from there?”
