When Hillary Clinton—the former first lady, Secretary of State and president-elect Donald Trump's Democratic opposition—arrived at today's inauguration ceremonies, she took to Twitter to elaborate on her presence:

One of the defining marks of American democracy, since it began, has been the concept of "peaceful transition of power." The former first family's presence is part of that tradition. Discuss

This election has brought a lot of firsts. The word "unprecedented" was one of the most used in coverage surrounding President-elect Donald Trump's election and The Washington Post reported there's another break in convention in the incoming administration.

For the first time in 29 years, the Presidential Cabinet will not include a Latino among his Cabinet nominees. This ends three decades of Latino secretaries, top ambassadors and administrators in previous administrations.

Roger C. Rocha Jr., national president of the League of United Latin American Citizens, spoke out against the break in precedent and said the lack of a Latino cabinet secretary “is a failure to ensure that the government is truly representative of the people it serves.”

Latino leaders met in Capitol Hill last week in an effort to urge the Trump transition team to find a Latino to include in the Cabinet nominations. On Wednesday, Trump transition officials confirmed the incoming President will nominate Sonny Perdue, former governor of Georgia, as the next agriculture secretary which completes the traditional White House Cabinet with the least diversity since the Reagan era.

The incoming Press Secretary Sean Spicer said Wednesday that Trump “has continued to seek out the best and the brightest to fill his Cabinet, but I don’t think that that’s the total reflection. We’ve got 5,000 positions. I think you’re going to see a very, very strong presence of the Hispanic community in his administration.” Discuss

Tomorrow, Donald Trump will be sworn in as the 45th president (as you've probably heard). As part of the ceremony, he'll swear on the Bible—in this case, two Bibles. The president-elect announced earlier this week that he plans to use his own Bible in addition to the same Bible used by Abraham Lincoln during his first inauguration in March of 1861.

The significance of Lincoln's Bible speaks for itself. As for Trump's own Bible, it's a Revised Standard Version he says his mother gave him when he graduated from Sunday school back in 1955.

Swearing on a Bible is a presidential inauguration tradition that goes back to George Washington. But not all presidents have chosen to swear on the Bible: Theodore Roosevelt, John Quincy Adams and Lydon B. Johnson are among those who didn't use a Bible in their inauguration ceremonies. Trump will be the fifth president, including Barack Obama, to swear on two Bibles.

Supreme Court Chief Justice John Roberts will conduct the ceremony. Discuss

A Secret Service discrimination case that has spanned more than 20 years was settled out of court for $24 million yesterday.

More than 100 black Secret Service agents argued that the security agency discriminated against black people by promoting less-qualified candidates over them from 1995 to 2005. The lawsuit began during the Clinton administration and was foisted off and delayed for several years as administrations and heads of the Secret Service changed.

Ray Moore, the lead plaintiff in the case, was part of President Clinton's security team and recalled putting in a bid for promotion 200 times and never being successful. White agents trained by him were often successful in being promoted over him.

Other plaintiffs also said they experienced the same thing, being passed over by unexperienced white agents who had lower performance ratings.

They also said the agency allowed a system of racism, including calling foreign leaders under their protection the n-word and, but the agents were told not to complain for fear of ruining their careers.

The agency has agreed to the settlement, but admits to no wrongdoing and no guilt of having an institutional bias within the ranks.

Jeh Johnson, the Homeland Security secretary who oversees the Secret Service, had his agency reopen this case to find a resolution before President Obama's term ended. In a statement, he said: “I am pleased that we are able to finally put this chapter of Secret Service history behind us. Had the matter gone to trial, it would have required that we re-live things long past, just at a time when the Secret Service is on the mend.”

The claim began with eight original plaintiffs, who will each get up to $300,000.

As part of the settlement, the Secret Service will have a new hotline for agents to report incidents and those incidents will be tracked when it comes time for those people to be promoted. Discuss

According to House Republicans, President-elect Donald Trump would prefer to build what he has referred to as the "Great Wall" between Mexico and the United States with taxpayer money through Congress. According to a report by CNN, Trump's administration would send the wall through the appropriations process as early as April.

After CNN reported that Trump's administration would ask taxpayers to pay for the wall, Trump got on Twitter to clarify his administration's plan and blame the "dishonest news media" for falsely reporting it by leaving off the fact that Mexico would be paying back the money.

Congress paying for the wall would move from Trump's repeated promises that Mexico would pay for the wall, though Mexico repeatedly said they definitely would not pay for it.

Former Mexican President Vicente Fox Quesada tweeted last night, re-affirming the general sentiment.

Chris Collins, the congressional liaison for the transition team, told CNN that Trump would be able to negotiate Trump Mexico paying the fees back:

When you understand that Mexico's economy is dependent upon U.S. consumers, Donald Trump has all the cards he needs to play. ... On the trade negotiation side, I don't think it's that difficult for Donald Trump to convince Mexico that it's in their best interest to reimburse us for building the wall.

Asking Congress paying for the wall could lead to other problems within the federal government. Democrats could refuse to pass the spending budget with the inclusion of funds for the wall, which could potentially lead to a government shutdown.

Throughout his campaign Trump promised the wall would be made of concrete, steel and rebar and would be as high as ceilings, with a "big, beautiful door" for documented immigrants to walk through.

Experts have long said that the wall would be unrealistic and Trump himself has frequently vacillated, saying the wall would not be the entire border length or could even be a fence instead of a wall. Discuss

Yesterday, Puerto Rico's Congressional representative turned in a bill to allow the island as the 51st state by 2025.

The only question now is what would happen to the flag?

Puerto Rico has long debated whether it would remain somewhat independent as a commonwealth or if it would try for statehood.

Currently the island is in a dire financial crisis that has sent more than 200,000 Puerto Ricans to the States recently and left the country with $70 billion of debt, according to ABCNews. Jennifer Gonzalez, the island's representative, said that as a state, Puerto Rico would get about $10 billion of federal funds annually.

Puerto Ricans are unable to vote in presidential elections, have less representation in Congress, but they still pay Social Security and Medicare taxes while receiving less funding from the federal government.

Most recently in 2012, voters in Puerto Rico said that they wanted to change their status from being a commonwealth, but there was no clear consensus on where to go from there. Discuss
