Judge orders ex-White House lawyer to testify in Congress
A US judge has ordered former White House counsel Donald McGahn to appear before Congress in a setback to Donald Trump's bid to keep top aides from testifying in impeachment hearings.
The decision could lead to renewed efforts by Democrats to compel evidence from other high-ranking officials, including former national security adviser John Bolton.
Judge Ketanji Brown Jackson ruled in a lawsuit filed by the House of Representatives Judiciary Committee.
Mr McGahn was a witness in the Mueller investigation, and Democrats want to question him about possible obstruction of justice by the president.
That was months before the House started impeachment hearings into Mr Trump's bid to get Ukraine to announce a probe of former vice president Joe Biden.
The ruling is likely to be appealed
