President Trump sued the IRS on Thursday, saying his own tax agency should pay him $10 billion for having allowed his private tax information to be leaked during his first term in office. Mr. Trump and sons Eric Trump and Donald Trump Jr. said the IRS gave access to Charles Littlejohn, a contractor who used his access to the IRS databases to hone in on Mr. Trump's tax information. He managed to exfiltrate it and deliver it to The New York Times, which published intimate details of the president's finances. Littlejohn would eventually be discovered, charged and convicted of the breach. He is serving a federal prison sentence.
