White House officials are already digging in their heels on a slew of requests related to Trump’s actions as president. The administration does not plan to turn over information being sought about how particular individuals received their security clearances, Trump’s meetings with foreign leaders and other topics that they plan to argue are subject to executive privilege, according to several aides familiar with internal discussions.

White House Counsel Pat Cipollone and the president’s legal team are preparing for an extensive legal battle, if necessary, over subpoenas from Congress, aides said.

On Monday, Trump’s private attorneys warned his accounting firm not to comply with a subpoena from the House Oversight and Reform Committee. Separately, two other House committees issued subpoenas to several banks Monday for information about Trump’s finances — drastically ratcheting up the stakes for the president, who is particularly angry about efforts to pry into his business, aides said.
