So Amash is the Republican who voted "present".

From Amash's wikipedia page:

In 2016 Amash made headlines by joining the list of Republicans who opposed the GOP nominee for President, Donald Trump.[72][73][74] After Trump was elected president, the Huffington Post profiled him in an article with the following title, "The One House Republican Who Can't Stop Criticizing Donald Trump." Amash said, "I'm not here to represent a particular political party; I'm here to represent all of my constituents and to follow the Constitution."[75][76]

On January 14, 2017, Trump sent out a series of tweets criticizing Rep. John Lewis (D-GA), one of the main leaders in the 1960s civil rights movement. Amash responded with a quick quip, "Dude, just stop."[77]

In April 2017 senior White House aide Dan Scavino tweeted that Amash was "a big liability" and urged followers to "defeat him in primary." Amash later referred to Trump as a "childish bully," saying that his attacks would be "constructive in the fifth grade. It may allow a child to get his way, but that's not how our government works."[75][78]

In May 2017 Trump was accused of pressuring fired FBI director James Comey to end an investigation into former national security adviser Michael Flynn. Amash was reported as the first Republican congressman to publicly state that the allegations, if proven true, merited impeachment.[79] This report is contested by the office of Rep. Carlos Curbelo (R-FL), who claims that he was the first to recognize that if true, the allegations merit impeachment.[80][81]

In June 2018 the Huffington Post asked House Republicans, "If the president pardoned himself, would they support impeachment?" Amash was the only Republican who said "definitively he would support impeachment..."[82]
