A federal judge has ruled President Trump can’t block top White House officials from testifying in the ongoing impeachment hearings. The judge’s reasoning: “Stated simply, the primary takeaway from the past 250 years of recorded American history is that presidents are not kings.” Judge Ketanji Brown Jackson’s ruling says former White House counsel Donald McGahn must comply with a congressional subpoena and testify to impeachment investigators about President Trump’s efforts to obstruct the Mueller inquiry. The Justice Department says it will appeal the decision. The ruling could have a sweeping impact on the impeachment hearings, where a number of top officials, including former national security adviser John Bolton, have so far refused to testify.

Meanwhile, federal prosecutors appear to be widening the probe into Trump’s personal attorney Rudy Giuliani. The Wall Street Journal reports recently issued subpoenas for people with ties to Giuliani suggest prosecutors may be investigating possible money laundering, obstruction of justice and campaign finance violations.
