This is a direct quote from a letter that I received from Pat Toomey (R- PA) last week:
"The president's actions were not "perfect." Some were inappropriate. But the question for the Senate was not whether his actions were perfect, but if they constituted impeachable offenses that justified removing a president for the first time and forbidding him from ever holding office."
Toomey's opinion is that the Democrats made a "...faulty claim that the only possible motive for his actions was his personal political gain. In fact, there are also legitimate national interests for seeking investigations into apparent corruption, especially when taxpayer dollars are involved."
I personally think this is hogwash: it was patently obvious that Trump had little or no concern of corruption in Ukraine in his first two years of office and that the only "corruption" Trump's personal lawyer was investigating pertained to the Bidens, his perceived political opponent in the 2020 election.
Toomey went onto quote none other than Joe Biden in his letter:
"Vice President Biden stated during President Clinton's impeachment trial, "the Constitution sets the bar for impeachment very high." A president can only be impeached and removed for "Treason, Bribery, or other high Crimes and Misdemeanors." While there's debate about the precise meaning of this phrase, it's clear that impeachable conduct must be comparable to the serious offenses of treason and bribery.
The Constitution sets the impeachment bar so high for good reasons. Removing a president from office, and forbidding him from seeking future office, overturns the results of the last election and denies Americans the right to vote for him in the next one. The Senate's impeachment power essentially allows 67 senators to substitute their judgment for that of millions of Americans.
Vice President Biden's framework for judging an impeachment was right then and it is right now."
So Toomey's position is that Trump's actions were "inappropriate" but did not warrant his removal of office.
