Donald Trump accepted assistance from Russia in the 2016 campaign and he is doing it again in the 2020 election when he pushed the President of Ukraine to investigate his political rival. He bribed that country by withholding military aid that Ukraine needed to help them with their war with Russia.
Only the most cynical partisan can make the case that that behavior by the President was OK. You need to look no further than the transcript summary the White House released for proof that he did it. He extorted Ukraine and it was an abuse of his power — end of story. Those who support Donald Trump with blind devotion cannot spin, twist, contort or skew this fact. For this action, he deserves to be impeached and any congressman who doesn’t vote for impeachment should not be re-elected.
