In a FOIA request dated March 29, EPIC called on the IRS to release Trump's tax returns from 2010 onward in an effort to find out if the president has any financial ties to Russia.

“The Commissioner should move promptly to obtain permission from the Joint Commission on Taxation to release the records EPIC has requested,” the FOIA said.
