The chorus calling for President Donald Trump's exit from the office has not only grown louder but has also changed tracks.

While the rhetoric earlier was a call to impeach the president, it has changed now to a demand for Trump's resignation.

This line was iterated in a campaign — #TrumpResign — started Sunday on Twitter by actor George Takei of "Star Trek" fame and “House of Cards” creator Beau Willimon.

On Sunday afternoon, playwright Willimon tweeted with the hashtag asking Trump to tender his resignation and "save whatever face you have left."

Takei soon joined in and tweeted using the hashtag, saying the best way forward for the country was without Trump.

The campaign soon gained momentum on Twitter, and by Sunday night it was one of the top ten trends in the U.S.

Some used #TrumpResign to make appeals to the president to resign, saying he had done enough damage to the country already.

Many listed the reasons for the president to leave office, pointing out the controversies he has created since becoming the president in January.

However, some used the campaign to express solidarity with Trump, saying it was started by "sore losers" liberals who were still upset after their drubbing in the 2016 election.

The crusade for Trump's ouster has been ongoing ever since he assumed office. It gathers intensity around every controversy that dogs the Trump administration. The recent trigger was Trump's failure to denounce white supremacists following the violence in Charlottesville, Virginia.

Joining those who denounced the president for his statements on the attacks, former vice president and climate change warrior Al Gore said Trump should resign when was asked by Britain's Lad Bible to give the president one piece of advice last week.

The same day, Tony Schwartz, ghostwriter of Donald Trump's memoir "The Art of the Deal," also reiterated his prediction that Trump will resign before the end of the year.

"Trump's presidency is effectively over. Would be amazed if he survives till end of the year. More likely resigns by fall, if not sooner," the author tweeted.

Schwartz said that he believed Trump would resign soon in an effort to "save face" before the Russia investigation by special counsel Robert Mueller came to an end. "The circle is closing at blinding speed. Trump is going to resign and declare victory before Mueller and congress leave him no choice," he said.

Former talk show host David Letterman echoed the same opinion on the "The Howard Stern Show" on Aug. 16, saying the "experiment hadn't worked."

"it's time to go... It was an experiment. We put an outsider in the office. Well, it hasn’t worked. Just resign." He added: “The impeachment thing will take forever and may not end with a conviction."

If Trump did indeed resign, Letterman said, “We’ll take it a step at a time. We’ll see what happens after that. But for the time being, we’ve had enough.”

The criticism came after Trump failed to condemn neo-Nazis and white supremacists and instead equated them with being on par with counter protesters in Charlottesville. Groups like the corporate America, civil rights activists , and a bipartisan band of politicians, —Republicans included—attacked the president.
