Booker says Mueller clearly suggests impeachment

WASHINGTON (AP) — Cory Booker is calling on fellow congressional Democrats "to begin impeachment proceedings immediately" in the wake of special counsel Robert Mueller's public statement on his investigation into Russian interference in the 2016 election, including the question of whether President Donald Trump obstructed justice.

The Democratic presidential candidate and New Jersey senator tweeted the statement Wednesday after Mueller spoke publicly for the first time since he was appointed two years ago.

Booker has previously declined to press for impeachment. But he said Mueller's statement "makes it clear: Congress has a legal and moral obligation" to initiate the impeachment process.

Mueller referred to a Justice Department legal opinion that says "the Constitution requires a process other than the criminal justice system to formally accuse a sitting president of wrongdoing."
