Imagine for a moment that it's Jan. 21, 2017. After a chilly inauguration the day before, the parades and festivities have ended. And the new president of the United States is ready for his or her first day of work.

"What follows is my 100-day action plan to make America great again," Donald Trump told supporters in Gettysburg, Pa., last weekend. "First I will announce my intention to totally renegotiate NAFTA, one of the worst deals our country has ever made."

Psy-ops in the guest box continues at the third and final presidential debate.

Donald Trump and Hillary Clinton are both using guest tickets in a calculated effort to rattle their rivals, or at least send a signal to voters watching on TV.

The in-your-face guest list includes two billionaire critics of Trump, the mother of a Benghazi victim, and President Obama's Kenya-born half-brother.

Live by the leak, and you may die by the leak.

That's the message Sen. Marco Rubio, R-Fla., is sending to his fellow Republicans, as he swears off using campaign material that originates with WikiLeaks.

"Today it is the Democrats. Tomorrow, it could be us," Rubio said in a statement.

Democratic vice presidential nominee Tim Kaine spoke to a church group in Miami over the weekend.

That wouldn't be remarkable except that he spoke entirely in Spanish — a first for a candidate on a major-party ticket.

First lady Michelle Obama joined students from across the country Thursday in picking produce from the White House garden. It's the last such harvest of the Obama era. But the first lady has taken steps to ensure the garden — and the bumper crop of publicity and goodwill it generated — won't disappear once she and her husband leave the White House.

Social Security alone consumes nearly a quarter of the federal budget.

At this week's vice presidential debate, Democrat Tim Kaine and Republican Mike Pence spoke about how the administrations they hope to join would deal with the challenges facing safety net programs like it.

The Challenge

RENEE MONTAGNE, HOST:

Republican presidential nominee Donald Trump may have been able to avoid paying income taxes for years. We don't know whether that's the case because Trump has not released his tax returns. But we know it's possible because some of Trump's tax documents from more than 20 years ago were made public over the weekend by The New York Times.

Republican presidential hopeful Donald Trump renewed his attacks on a former Miss Universe winner Friday, heedless of the possible fallout with women and Latino voters.

In a series of tweets posted around 5 a.m. ET, Trump criticized Alicia Machado as "my worst Miss U." and described her as "disgusting."

The Arizona Republic has endorsed Hillary Clinton for president — the first time the newspaper has backed a Democrat in its history.

The Republic's editorial board writes that Clinton understands what the position demands: "a steady hand, a cool head, and the ability to think carefully before acting." And it pointedly concludes that her Republican rival, Donald Trump, does not.

Jordan Weaver was just a kid when Barack Obama was elected eight years ago. But she'll never forget that November night.

"My biggest memory is us in my living room," said Weaver, who grew up in Harrisburg, Penn. "My mom was crying. She was so happy that a president could be African-American and people accepted him. You could just see that everyone was so excited."

Eight years later, Weaver joined thousands of people who turned out to see Obama speak in Philadelphia earlier this week.

Republican presidential hopeful Donald Trump offered a bold prediction Thursday that his economic plan will deliver up to 25 million new jobs over the next decade. He described the blueprint as "the most pro-growth, pro-jobs, pro-family plan put forth perhaps in the history of our country."

Former Secretary of State Colin Powell used a personal computer connected to a private telephone line to send and receive emails to staffers, friends and foreign leaders without having to go through State Department servers.

Powell shared that experience with Hillary Clinton two days after she took over as secretary of state. Powell cautioned Clinton to "be very careful," lest her emails be discovered and become part of the official State Department record.

President Obama repeated his argument that Donald Trump is not qualified to be president.

He urged both voters and journalists to pay careful attention to what he called Trump's "uninformed or outright wacky ideas," and not to grade the Republican White House nominee "on a curve."

Libertarian presidential nominee Gary Johnson asked a television interviewer Thursday, "What is Aleppo?" betraying a lack of interest or even superficial knowledge of the civil war in Syria that has been raging for more than five years.

The question came during an interview on MSNBC's Morning Joe. Panelist Mike Barnicle asked the two-time Libertarian nominee and former governor of New Mexico, "What would you do if you were elected, about Aleppo?"

Hillary Clinton told FBI investigators no one at the State Department raised concerns with her about using private email servers to conduct government business during her time as secretary of state.

Clinton repeatedly told investigators she relied on seasoned professionals at the department to ensure that classified information was handled properly. And she insisted her use of the private server was for convenience, not an attempt to evade Freedom of Information Act requests or government record-keeping laws.

To carry out his hard-line immigration policy, Donald Trump proposed hiring 5,000 additional Border Patrol agents and tripling the number of "deportation officers."

But that would continue an already decade-long expansion of the government agencies responsible for those tasks — even as the number of illegal border crossers has shrunk dramatically. That's not even to mention the billions of dollars it would cost to build a brick-and-mortar wall across the length of the entire U.S.-Mexico border.

Here are six things to consider:

In a speech Wednesday night, Donald Trump will lay out — and clarify — his proposed immigration policy.

His stance on immigration has appeared to change more in the past 10 days than it has in the past 10 months.

But perhaps the most unexpected element of the recent shifts in rhetoric is that Trump has praised President Obama's work on immigration enforcement, a surprising turn for a Republican candidate.

Republican presidential nominee Donald Trump is shaking up his campaign staff, after a series of missteps that led to slumping poll numbers.

Trump has tapped Stephen Bannon of Breitbart News to serve as chief executive of the campaign. Pollster Kellyanne Conway was promoted to campaign manager. Paul Manafort will stay on as Trump's campaign chairman. The Wall Street Journal first reported the news.

For a man once accused of forming every sentence with a noun, a verb and 9/11, it was a serious omission.

Republican presidential hopeful Donald Trump said Monday it's time to "chart a new course" in the battle against "radical Islamic terrorism," though much of what he proposed is similar to the course already set by President Obama.

The chairman of Donald Trump's presidential campaign says he never received a single off-the-books cash payment for political work in Ukraine.

The statement from campaign chairman Paul Manafort comes after The New York Times reported that his name appears in a so-called "black ledger" recording under-the-table payments made by the political party of Ukraine's former pro-Russian president, Viktor Yanukovych.
