A recent uptick in border-crossings by illegal aliens is proof to some that President Donald Trump's tough rhetoric is starting to wear off.
Supporters of a border wall say it's time to show the U.S. is serious about securing its southern boundary, especially with talks of amnesty still lingering.
"We have seen around the world that walls and fences are effective, you know it's not just the United States that has pursued these policies," says Ira Mehlman with the Federation for American Immigration Reform.
And this isn't the first time a border fence has been proposed in the U.S.
"It had the support of the current Senate Minority Leader Chuck Schumer, then senators Barack Obama, Hillary Clinton and Joe Biden all voted for it," says Mehlman. "It was a good idea back in 2006 and it's still a good idea in 2017.
But he says the visa program also needs fixing.
"It's really incumbent upon the United States to demonstrate to people not just in words, but through deeds, that we're not going to tolerate rampant disregard for immigration laws."
Meanwhile, border arrests were up 60 percent over the summer.
