"Our leaders must restore the luster and dignity of the institution of the Presidency." 

Vice President Mike Pence argued that the president must be held to the highest moral standards in a pair of columns from the 1990s. 

Pence -- who is ​known for his devotion to faith, family and values -- wrote the columns when he was the host of an Indiana radio show during the height of President Bill Clinton's ​scandal with Monica Lewinsky. He made the case that Clinton should be removed from office because the integrity of the presidency had been lost.

"Throughout our history, we have seen the presidency as the repository of all of our highest hopes and ideals and values. To demand less is to do an injustice to the blood that bought our freedoms," Pence wrote in a ​column titled "The Two Schools of Thought on Clinton." 

Pence explained that the president should be held to higher standards than an average citizen.

"If you and I fall into bad moral habits, we can harm our families, our employers and our friends. The President of the United States can incinerate the planet," he wrote. "Seriously, the very idea that we ought to have at or less than the same moral demands placed on the Chief Executive that we place on our next door neighbor is ludicrous and dangerous."

The resurfaced Pence columns arguing that impeachment is a justifiable remedy for an immoral president coincide with some Democrats calling for the ​impeachment of President Donald Trump.

Trump's personal morals have been heavily scrutinized. The president has been plagued by  ​allegati​o​ns of ​affairs with adult film star Stormy Daniels and former Playboy model Karen McDougal, as well as ​accusations of sexual harassment from several women.

Commentators on Twitter accused Pence -- who has been relatively quiet on concerns regarding Trump's moral failings  -- of hypocrisy. 

In a ​column titled, "Why Clinton Must Resign or be Impeached," Pence called on lawmakers to take action.

"Our leaders must either act to restore the luster and dignity of the institution of the Presidency or we can be certain that this is only the beginning of an even more difficult time for our land."
