Actress Evan Rachel Wood, a star in the HBO series "Westworld," took part in a hunger strike to protest President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

The strike, which was partially organized by the Robert F. Kennedy Human Rights organization, began on Saturday in McAllen, Texas, and lasted 24 hours to commemorate the roughly 2,400 children that were separated from their parents as a result of the Trump administration's policy.

Wood, who took a tour across Texas over the weekend and visited a shelter in McAllen on Sunday, told People Magazine that it was a “privilege and not a sacrifice” to take part in the protest.

“It’s a small price to pay considering what families are going through,” she said.

People reported that Wood delivered supplies and met some of the immigrant families who have been released from detainment during her visit.

“[I wanted] to put faces with the stories,” she says, “[and] to actually be there and hug the children and play with them, see how sweet and loving they are but to see how tired and in pain they are — and see the fear in their parents’ eyes.”

In addition to Wood, Actors Levar Burton, Alec Baldwin and Martin Sheen all participated in the hunger strike, according to USA Today.

The protests came just days after Trump signed an executive order to end his administration's policy of separating families who entered the country illegally. Trump made the decision after facing increasing backlash from Republican and Democratic lawmakers.

The Department of Homeland Security (DHS) says that it knows the locations of every child separated from their parent at the border. But it has yet to provide a clear outline for how it intends to reunite those families.

Despite the plans to reunify families, Trump has continued to rail against America's immigration system. He's accused Democrats of being weak on crime and has heightened his calls for increased border security. On Sunday, he tweeted that "We cannot allow all of these people to invade our Country. When somebody comes in, we must immediately, with no Judges or Court Cases, bring them back from where they came."
