White House says it will not cooperate with impeachment inquiry

The White House delivered a letter to the House, saying it would not cooperate with its impeachment inquiry. In the letter, the White House called the impeachment an illegitimate effort to overturn the results of the 2016 election. President Trump called it a “kangaroo court,” with the letter and his comments setting up a constitutional battle over impeachment. Constitutional expert Robert McWhirter talks about Congress’s right to call for impeachment of a president and whether Trump’s claims have any merit.
