Hillary Clinton has apologized to immigrants for using the term "illegal" when referring to them.

"That was a poor choice of words. As I've said throughout this campaign, the people at the heart of this issue are children, parents, families, DREAMers. They have names, and hopes and dreams that deserve to be respected," Clinton said during a Tuesday Facebook Q&A with Noticias Telemundo, an NBC-affiliated Spanish-language network.

According to NBC News, the Democratic frontrunner was criticized for using the phrase at a campaign stop in Windham, New Hampshire, where she said, "I voted numerous times when I was a senator to spend money to build a barrier to try to prevent illegal immigrants from coming in."

Responding to a question from immigration rights activist Jose Antonio Vargas, Clinton said that she has discussed undocumented immigrants "hundreds of times and fought for years for comprehensive immigration reform," NBC News reported.

In her Facebook Q&A, Clinton answered other queries about broad immigration reform and the economy, giving emphasis to the United States as "a country built by immigrants and our diversity makes us stronger as a nation - it's something to be proud of, celebrate, and defend," the news outlet added.

Clinton also received questions about Republican presidential candidate Donald Trump and his anti-immigrant rhetoric. One woman wrote in Spanish that she hoped Clinton would stand with the undocumented population because Trump treats them "like second-class citizens."

"I have just one word for Mr. Trump: Basta. Enough is enough. He's been trafficking in prejudice and paranoia and it's bad for our politics and bad for our country," the former Secretary of State replied, as quoted by NBC News.

This week, Clinton launched a new political strategy called "Mujeres in Politics," a national group expansion of her campaign strategy to woo the women of the U.S. Latino population.

The strategy was "designed for Latinas to speak to Latinas about the fights they are waging and the importance of their civic participation," New York City Council Speaker Melissa Mark-Viverito said, according to a separate report by NBC News.

She continued, "Latinas are the CEOs of their family and community and will play a critical role in securing the nomination."

Clinton Nabs Another Major Endorsement

Clinton nabbed another endorsement from a major labor union this week. On Tuesday, the Laborers' International Union of North America, or LIUNA, chose to back Clinton rather than other Democratic presidential candidates Bernie Sanders and Martin O'Malley, the Huffington Post reported.

LIUNA said in a statement that Clinton's record "proves that she is a tough and tested fighter for our nation and for working men and women," the Huffington Post added.
