Rep. Mike Coffman (R-CO), who has signed the discharge petition, opposed Trump so much in the 2016 election that he ran ad campaigns against him.
Upton refused to endorse Trump during the 2016 presidential election, saying he was “gonna stay in my lane”:
A fellow signer of the discharge petition is Rep. Charlie Dent (R-PA), who slammed Trump during the 2016 presidential election and said his various comments on the campaign trail were “too much.” Dent is retiring from Congress and even partially blamed Trump for his departure.
Another discharge petition signer, Rep. Ryan Costello (R-PA), did support Trump against Hillary Clinton in the 2016 presidential election but backed off that support in the months leading up to the election.
Rep. David Valadao (R-CA), also a signer of the discharge petition, dropped his endorsement of Trump in 2016, saying, “I am disappointed with the divisive rhetoric coming from this Presidential Election and cannot support either candidate.”
