Donald Trump Inauguration update: performers, legislators and activists are all getting themselves involved or not involved due to varied reasons

The tumultuous two-year period starting from Donald Trump's declaration of his candidacy to the highly divisive campaign period and the controversial win — everything seems to have accumulated at the upcoming President-elect Inauguration.

But even the last couple of days before the Republican assumes office are proving to be trying times for Trump as his team struggled in booking performers to celebrate with him come Friday. So far only Travis Greene, Sam Moore, Jackie Evancho, Lee Greenwood, 3 Doors Down, the Piano Guys, DJ Ravidrums, the Frontmen of Country, Jon Voight and Toby Keith have confirmed for the gig. Keith then follows defending up his decision to partake in the Inauguration.

Keith then follows defending up his decision to partake in the Inauguration.

"I don't apologize for performing for our country or military," the country singer boldly said in a statement sent to Entertainment Weekly. "I performed at events for previous presidents [George W.] Bush and [Barack] Obama and over 200 shows in Iraq and Afghanistan for the USO."

The list for those who either flatly declined, backed out or just could not accommodate the event due to schedule conflict were A-list names, which include Celine Dion, Andrea Bocelli, Sir Elton John, David Foster and most recently Jennifer Holliday who has decided to pull out from the event due to a heartfelt letter sent to her detailing the worries of the lesbian, gay, bisexual and transgender (LGBT) community with Trump as the head of state.

Aside from the stars and celebrities, more and more politicians are also sitting out the 45th President's Inauguration fueled by the businessman-turned-politician blasting civil rights legend Rep. John Lewis. Rep. Yvette Clarke of New York, Rep. Maxine Waters of California and Rep. Mark Pocan of Wisconsin have all stated via their social media that they will not be in DC for Trump's event.

Meanwhile, it appears that there will be no shortage of citizens partaking in the Inauguration with a possible record-breaking number of activists going out on the streets to protest.

"Based upon what I've read and the number of people that I've heard will be coming to protest the inauguration, it sounds like this will be the all-time record," Jim Bendat, author of "Democracy's Big Day: The Inauguration of Our President, 1789-2013" told The Washington Times. "Police estimated [25,000 to] 30,000 protesters at Nixon's second inauguration," Mr. Bendat said. "I think there were around 20,000 for one of George W. Bush's. The numbers could reach and surpass that this year.

Trump who is taking over outgoing President Barack Obama's post is assuming office with a historically low approval rating. Courtesy of the CNN/ORC poll, just 44% of the surveyed sample size American favors the incoming POTUS with ABC News/Washington Post poll even dipping to just 40%.

President-elect Donald Trump's Inauguration will be held on Friday, Jan. 20, on the West Front of the United States Capitol Building in Washington, D.C.
