Dr. Ahmed al Shanti, a Palestinian living in the United Kingdom, told ABC News on Wednesday that his family in Gaza were both "surprised" and "devastated" by Trump's latest comments and expressed fears of ethnic cleansing.

“Suggesting these ideas might get young people in Gaza excited to leave for a better future, but at the same time there is a large percentage of people in Gaza who are third- and second-generation, the idea of being ethnically cleansed again is not off the table," he said.

He explained how “people in Gaza expected the Western countries to finally support their rights to have self-determination and above all of that help to rebuild Gaza as they have helped Israel destroying it.”

He also outlined the many questions he said Palestinians are wondering about:

“Does that mean they are forcibly displacing us? Will the war continue and the army will push people outside Gaza?” he asked. “They also think the idea of rebuilding Gaza was a lie.”

Texas Democratic Rep. Al Green announced Wednesday he intends to file articles of impeachment against Trump once again, stemming from his proposal to take over Gaza.

"I rise to announce that I will bring articles of impeachment against the president for dastardly deeds proposed and dastardly deeds done," Green said on the House floor.

With a Republican majority in both the House and the Senate, it is almost certain that Green's efforts will go nowhere. During Trump's first term, Green made various impeachment pushes, which all failed.

"I did it before. I laid the foundation for impeachment, and it was done. Nobody knows more about it than I, and I know that it's time for us to lay the foundation again,” Green said, emphasizing that he stands for justice.

Senate Majority Leader John Thune gave brief comments Wednesday morning on Trump's proposed takeover of Gaza, suggesting that the president has "put some ideas out there" to bring peace to the region.

Thune told reporters on Capitol Hill that Trump "wants to bring a more peaceful, secure Middle East, and he’s put some ideas out there."

He later doubled down on that sentiment, saying, “look there are a lot of ideas that are coming out to try to address what is clearly a crisis in that region.”

Palestinians have reacted with defiance to Trump's stunning announcement that the U.S. would "take over" Gaza.

Tala Herzallah, a 22-year-old student in Gaza, said it felt like a slap on her face after everything Palestinians have endured for over a year.

"You wake up with a slap on your face after knowing the solution of the president of the United States to us: Just leave your homeland, leave your country for us to rebuild it in a way that we see is good. For us, not for you," she said, adding that she "can't understand how this can be considered justice."

Palestinians also reiterated their resolve to remain in their homeland. 28-year-old Osama said "we will certainly not leave Gaza," adding that they "will rebuild it and never leave it."

"I will not leave, it is impossible, I will sacrifice my blood in order to stay here in my land," said Muhammad Zarouk, a resident of Al-Shati Camp.

"I am used to scary, I don't mind, to be honest. Whatever happens will just happen, we can't control anything," 19-year-old Malik said, adding that "the situation here is much more difficult than you imagine."
