GRAND RAPIDS, Mich. (WOOD)  In a pair of late Sunday morning tweets, President Donald Trump responded to statements from West Michigan Congressman Justin Amash, R-Cascade, who accused the president of “impeachable” behavior.

Amash put out a series of tweets Saturday summarizing his take on Special Counsel Robert Mueller’s report on the investigation into Russian interference in the 2016 election and the possible collusion by President Trump and his campaign.

In one of the tweets Amash said “President Trump has engaged in impeachable conduct.”

“Contrary to Barr’s portrayal, Mueller’s report reveals that President Trump engaged in specific actions and a pattern of behavior that meet the threshold for impeachment,” Amash tweeted.

The statements make Amash the first republican congressman to publicly state that Trump’s behavior uncovered in the investigation was impeachable.

The president was brash in his rebuke of Amash’s remarks Sunday morning.

“Never a fan of , a total lightweight who opposes me and some of our great Republican ideas and policies just for the sake of getting his name out there through controversy. If he actually read the biased Mueller Report, “composed” by 18 Angry Dems who hated Trump,….,” the president’s first post on Twitter said.

….he would see that it was nevertheless strong on NO COLLUSION and, ultimately, NO OBSTRUCTION…Anyway, how do you Obstruct when there is no crime and, in fact, the crimes were committed by the other side? Justin is a loser who sadly plays right into our opponents hands,” he continued.

Amash has been critical of the president in the past and some say it has isolated him among republicans in congress.

Others opine that Amash’s latest statement set him up for a primary challenger in the next years elections.

Some of Amash’s fellow republicans have been openly critical of his remarks. Jim Saalfeld, a republican Kent County Commissioner, accused Amash of being a libertarian committing a “fraud” on the voters by running as a republican.

Michigan GOP Chair Laura Cox made a statement on Twitter late Saturday night.

“While President ’s leadership has led to the strongest economy in a generation, Justin Amash has opposed his ‘America First’ agenda every step of the way,” Cox wrote. “Now, in a desperate attempt to grab headlines and advance his own presidential ambitions, Amash is peddling a narrative that has repeatedly been proven false. Shameful.”

Brian Patrick, communications director for Rep. Bill Huizenga, R-Zeeland, released remarks that sounded like a dare.

“Any member of Congress has the ability to file articles of impeachment at any time if they believe such a charge is warranted,” Patrick said in written statement. “Bill has said publicly that he is not aware of any impeachable offense.

Amash and his spokesperson did not respond to 24 Hour News 8 interview requests following his controversial statements.
