WASHINGTON -- As news spread of President Donald Trump's decision to fire FBI Director James Comey, U.S. Rep. Justin Amash from Michigan's 3rd District says an independent commission needs to continue the investigation into Russia.

My staff and I are reviewing legislation to establish an independent commission on Russia. The second paragraph of this letter is bizarre. https://t.co/wXeDtVIQiP — Justin Amash (@justinamash) May 9, 2017

Amash took to Twitter Tuesday night to announce the decision to look into possible legislation after CNN tweeted Trump's letter dismissing Comey.

The second paragraph of the letter appears to be the catalyst for Amash's announcement.

"While I greatly appreciate you informing me, on three separate occasions that I am not under investigation, I nevertheless concur with the judgment of the Department of Justice that you are not able to effectively lead the Bureau," Trump wrote.

Amash called that paragraph "bizarre."

Since the firing was announced, there's been speculation from Trump's critics about the timing of the dismissal, as Comey and the FBI have been investigating ties between associates of Trump and Russia in relation election tampering last fall.

"The decision by a President whose campaign associates are under investigation by the FBI for collusion with Russia to fire the man overseeing that investigation, upon the recommendation of an Attorney General who has recused himself from that investigation, raises profound questions about whether the White House is brazenly interfering in a criminal matter," said U.S. Rep. Adam B. Schiff D-Calif., in a statement.

While Trump himself has not been named as being under investigation, aides who worked on the campaign and some of the people involved with his administration have been scrutinized.

The Washington Post reports that Comey was fired because senior Justice Department officials believe he violated Justice Department principles and procedures discussing the investigation of Hillary Clinton's use of a private email server.

Although Amash is a Republican, he's been hesitant to jump on board with all parts of Trump's agenda. He notably did not show support for Trump's first attempt at repealing and replacing the Affordable Care Act in March.
