BOSTON, Mass. (WWLP)--Inauguration Day is in full swing in Washington, D.C., marking the handover of power to the incoming Trump-Vance administration. Although this is Donald Trump’s second inauguration, there are some notable differences from his first. Perhaps most obvious–Trump has a new Vice President in J.D. Vance.  Governor Healey attending Martin Luther King Jr. Day event in Springfield Changing vice presidents in a second term is not unheard of. Most recently, President Richard Nixon served alongside Spiro Agnew in his first term beginning in 1969 and Gerald Ford in his abbreviated second term before resigning in 1974. In the case of Trump and former Vice President Mike Pence, Pence says in his memoir “So Help Me God” that Trump's massive push to overhaul the results of the 2020 election marked the end of their political collaboration. Pence says Trump endangered all on Capitol Hill by inciting the January 6, 2021 riots. The former Vice President’s replacement, Vance, a conservative junior Senator from Ohio, used to be a harsh Trump critic. In Trump’s campaign, he energized Trump’s far-right base. After Vance and Trump were sworn in around noon, Trump delivered the first address of his second presidency.  His 2017 address was marked by dark undertones, standing in contrast to the tradition of uplifting and positive speeches by previous presidents. He painted pictures of poverty and desolation in the United States, and positioned himself as the solution. “The American carnage stops right here, right now. From this day forward, a new vision will govern our land. From this day forward, it's going to be only America first. America first,” Trump said in his 2017 address. This year, he revisited his America first rhetoric, but his speech overall focused more on moving forward and excitement for the future. Trump referenced an assassination attempt he survived at a Pennsylvania rally this summer, saying he was “saved by God to make America great again.”  He also declared January 20, 2025 “American Liberation Day,” and recognized Martin Luther King Jr. Day by saying he is looking forward to making the Civil Rights leader’s “dreams come true.”  At Trump’s first inauguration in 2017, crowd turnout was estimated to be 720,000 individuals. Trump’s then-press secretary claimed the actual turnout was the largest in history, but later walked back these remarks. This year, counting the crowd could be more complicated. While inaugurations are traditionally held on the Capitol steps with onlookers spread across the National Mall, severe cold forced the ceremonies inside the building this year.  The presidential parade will take place inside the Capitol One Arena, where onlookers can congregate, instead of on Pennsylvania Ave. Trump warned National Mall-goers to dress warmly, but due to the spread out nature of this year’s events, turnout estimates will likely come in later than in previous years. Trump’s second presidency will be his last, due to 1956’s 22nd Amendment to the Constitution, barring presidents from serving more than two terms.  Fourteen presidents have served at least two full terms, with Franklin D. Roosevelt serving 3 terms and 2 months of a fourth term before his death. Following Roosevelt’s four inaugurations, the United State adopted the Constitutional amendment limiting each president to two terms.  Seven more presidents have either succeeded a president in a term and gone on to win a second, or won a first term and died during their second.  The remaining 23 presidents served one term or a partial term.  Donald Trump, both the country’s 45th and 47th president, is one of two presidents to be elected to two non-consecutive terms, joining Grover Cleveland.
