WASHINGTON—Over his nearly three years in office, lawyers representing President Trump have made numerous legal arguments that, taken as a whole, would give the president sweeping immunity—even if he were to commit murder.
An extensive review of correspondence, court documents, legal opinions and public statements from lawyers representing Mr. Trump shows the president’s attorneys have consistently pushed to put him beyond the reach of any other institution in federal, state or local government—immune to civil lawsuits, judicial orders, criminal investigations or congressional probes.
Those arguments have become even more aggressive as Mr. Trump faces numerous legal threats, including a possible impeachment in Congress, a New York state prosecutor who has subpoenaed his tax records as part of a criminal probe and a welter of civil lawsuits.
One lawyer for the president recently went so far as to suggest that Mr. Trump could shoot someone on Manhattan’s Fifth Avenue and not be investigated by local authorities, echoing a statement the president made during his 2016 campaign in which he said he wouldn’t lose any voters over such an action.
“This administration has articulated a view of presidential power in which the president is above the law,” said Erica Newland, who served in the Justice Department Office of Legal Counsel during both the Obama and Trump administrations.
