Lawyers for Donald Trump are engaged in talks with the IRS to resolve a $10 billion lawsuit the president filed against his own tax collection agency over the leak of his tax information to news outlets between 2018 and 2020.

In a federal court filing Friday, Trump asks a judge to pause the case for 90 days while the two sides work to reach a settlement or resolution.

Tax and ethics experts say the lawsuit raises a plethora of legal and ethical questions, including the propriety of the leader of the executive branch pursuing scorched-earth litigation against the very government he oversees.
