The Internal Revenue Service and the White House squabbled over the use of tax data to find suspected undocumented immigrants just hours before Trump administration officials pushed out IRS Commissioner Billy Long on Friday, according to a new report Saturday.

The Trump administration’s move to push out IRS Commissioner Billy Long came after the agency said it couldn’t release some information on taxpayers suspected of being here illegally.

The IRS previously agreed to a data-sharing scheme with the Department of Homeland Security to use some sensitive information to identify illegal immigrants.
