Donald Trump’s pick to head the Internal Revenue Service pressed the agency to investigate and consider stripping the country’s leading animal welfare group of its tax status after it supported an initiative to protect dogs, according to documents reviewed by The Lever.

If former Missouri Republican Rep. Billy Long is confirmed to run the Internal Revenue Services (IRS), he would be in a position to strip — and effectively shut down — the tax status of such nonprofit groups whose missions he disagrees with. And Long could have new powers to do so if Congress enacts a pending House-passed bill to grant the Trump administration new powers to rescind the tax status of groups it deems “terrorist supporting organizations.”
