Pennsylvania’s federal lawmakers are split down party lines with the impeachment inquiry into President Donald Trump.

Republicans U.S. Sen. Pat Toomey and Rep. Glenn Thompson both said Trump’s phone call with President Volodymyr Zelensky of Ukraine did not rise to the level of impeachment.

“The memorandum released by the White House today reveals no quid pro quo,” Toomey said. “While the conversation reported in the memorandum relating to alleged Ukrainian corruption and Vice President Biden’s son was inappropriate, it does not rise to the level of an impeachable offense.”

Meanwhile, Thompson called the inquiry a “stunt” and had some harsh words for Congressional Democrats.

“Speaker Pelosi may have formally announced an impeachment inquiry yesterday, but it’s clear this stunt began on January 20, 2017. There are some in Congress who simply cannot accept the outcome of the presidential election,” Thompson said.

“You heard collusion, conspiracy, and doing away with the electoral college,” he said, listing off things raised by the Democrats since Trump was elected.

“Now you’re going to hear impeachment, term limits for the Supreme Court, and other socialist ideas with the only goal of winning elections,” the congressman said. “What we’re not hearing are the best and brightest ideas on how to better the lives of everyday people who are just trying to get a leg up, support their families, and live in safe communities.”

As for Pennsylvania’s Democratic U.S. senator, Bob Casey, a vocal critic of Trump, he said he was in support of the inquiry, as his concerns with Trump’s conduct have continued to mount.

“The recent revelation that President Trump pressured a foreign government to investigate his political opponents is a textbook case of abuse of power which demands action,” Casey said in a statement.

Speaking to the media Wednesday afternoon, Casey said, “The president has demonstrated in real time that he’s willing to abuse his power to advance his political interests. There is a textbook case of abuse of power and the only way to stop it is to take action.

“It is clear to me that the president is willing to abuse his power with impunity,” he continued. Casey brought up the report by Special Counsel Robert Mueller as well, saying Trump didn’t seem to learn from it.

“He doesn’t seem to have gotten the message from the Mueller report that his actions should be in the national interests, not in his political interests,” Casey opined. “He’s apparently ready, willing and able to continually abuse his power to advance his political interests.”

He added that it is critical to send a message that improper conduct by public officials will not be tolerated.

“We have to take action now to send a very clear signal not only to the president, but to future presidents and any public official, that this conduct is totally inappropriate and it’s impeachable,” the senator said.

In his written statement, Casey outlined what impeachment means, including the reasons for it — “treason, bribery or other high crimes and misdemeanors.”

He mentioned, too, the three times the impeachment process has been used in the past — in 1868 with President Andrew Johnson, in the Watergate era with President Richard Nixon and in the 1990s with President Bill Clinton.

“When Special Counsel Mueller issued his report on Russia’s interference in the 2016 election and more recently as reporting has emerged about President Trump’s conduct towards Ukraine, I have attempted to assess how President Trump’s actions fit into our historical and current understanding of ‘high crimes and misdemeanors,’” Casey said.

He continued, saying impeachment should not be taken lightly, or used in a “cavalier fashion,” which would be an insult to the Constitution. “However, a failure by Congress to pursue impeachment in the face of grave offenses by the President is just as insulting to our Constitution and our values.”

The senator ended his statement with an historical quote.

“As our Founders debated the merits of impeachment during the during the 1787 Constitutional Convention in Philadelphia, Elbridge Gerry rose and offered a powerful justification for including such a provision in the final Constitution: ‘A good magistrate will not fear [impeachments]. A bad one ought to be kept in fear of them.’ In the face of such blatant abuse of power and self-interested violations of the public trust — high crimes and misdemeanors — Congress must act.”
