Lankford wouldn't weigh in on whether Trump's aggressive immigration enforcement efforts - including ending protections for hundreds of thousands of Central Americans who have been living and working in the United States legally for close to two decades - are harmful to Central America.
"Those young people are the future", said Hidalgo, whose online biography says she grew up in Colombia, Peru and Mexico before immigrating to the United States and later becoming a USA citizen.
And in the name of halting illegal immigration, he has also demanded Congress budget $25 billion for a "trust fund" for constructing a wall on the US-Mexico border - a major plank of Trump's White House campaign.
"Being able to live in this country means everything to me because I came at a young age so this is the only country that I know", said Danyel Daniele, who was brought to the US illegally from Venezuela when he was 3.
"Trump destroyed DACA, threatened Dreamers with detention and deportation, and is using that threat to enact his hardline immigration policies", said Rep. Michelle Lujan Grisham, D-N.M., chair of the Congressional Hispanic Caucus.

The Senate's top Democrat, Chuck Schumer of NY, dismissed the plan Friday as a "wish list" for hard-liners. And for some Democrats the window of bipartisan outreach seems to have closed.
