In his 2018 campaign for Senate, Manchin said he supported Trump's proposal to construct a border wall along the southern border of the continental United States. He also said that he regretted voting for Hillary Clinton and would be open to supporting Trump for president in 2020. But he ultimately voted with all Democratic senators to convict Trump in his first impeachment trial for abuse of power and obstruction of Congress, and later said that he supported Joe Biden for president in 2020.
