On Wednesday, Rep. Brad Sherman (D-Calif.) introduced an article of impeachment in the House, seeking to remove President Donald Trump from office for obstruction of justice. Rep. Al Green (D-Texas) co-sponsored the article.

Sherman first raised the specter of impeachment in early June , basing his case on Trumps apparent interference in an FBI investigation into his former national security advisor, Michael Flynn.

As Sherman sees it, Trumps firing of FBI Director James Comey who says he was fired in retaliation for continuing to investigate Flynn constitutes obstruction of justice.

Recent disclosures by Donald Trump Jr. indicate that Trumps campaign was eager to receive assistance from Russia, Sherman explained in a media release. It now seems likely that the President had something to hide when he tried to curtail the investigation of National Security Advisor Michael Flynn and the wider Russian probe. I believe his conversations with, and subsequent firing of, FBI Director James Comey constitute Obstruction of Justice.

While Sherman said Trump has also engaged in all manner of decidedly unpresidential conduct, he acknowledged that doesnt constitute an impeachable offense.

The Constitution does not provide for the removal of a President for impulsive, ignorant incompetence, he wrote. It does provide for the removal of a President for High Crimes and Misdemeanors.
