"There are different points of view about how to address that, and all of that will be dealt with publicly on the floor before we have the vote", the Kentucky lawmaker said.
"This is one where he tried to be reasonable, and I think his opposition was unreasonable".
In the Senate, more Republicans have expressed concerns about setting a unsafe precedent, and Vice-President Mike Pence met members during a closed-door lunch on Tuesday to discuss the issue.
The resolution is expected to sail easily through the Democrat-controlled House.
Republican Senator Thom Tillis, in an op-ed published in Tuesday's Washington Post, said he backed Trump on border security issues but would vote for the resolution because he "cannot justify providing the executive with more ways to bypass Congress".
President Trump has been criticized for using the emergency declaration as a way to push his agenda. They "would love the opportunity to oppose him", Amash added, but "they're not going to take it for political purposes".
If all Senate Democrats support the resolution, only four Republicans would be needed for it to pass the Senate.
Republican Senator Lindsey Graham has said a "handful" of Republicans would likely vote for the resolution.
Black Panther Becomes Marvel Studios' First Oscar Winner
She continued, "Marvel may have made the first black superhero, but through costume design we turned him into an African king". Black Panther made history at the Oscars after becoming the first Marvel movie to win an Academy Award .
So far, three - Lisa Murkowski of Alaska, Susan Collins of ME, and Thom Tillis of North Carolina - have already indicated they will vote to block Mr Trump's order.
The US House of Representatives is expected to vote to block President Donald Trump's emergency declaration over building a US-Mexico border wall.
As for the Republican spin, White House adviser Stephen Miller claimed the illegal immigration population under President George W. Bush doubled from 6 million to 12 million by the time Bush left office.
Trump has argued since his campaign for president that the United States needs a wall along its border with Mexico to stop people from entering the country illegally and to halt the flow of drugs.
Now the resolution will be discussed in the Senate where only a simple majority is required to pass. To override that, two-thirds of both chambers of Congress would need to vote in favor of the resolution after Trump vetoes it. It is doubtful that Congress could muster the votes to override him. But two years on, as President Trump dreams of conferring extraordinary powers to the executive - taking control of broadcast networks and creating internment camps for immigrant children - Democrats have taken a new tack: challenging Republicans to choose between their loyalty to Trump and their oath to uphold the U.S. Constitution.
Congress passed a bipartisan spending bill the day before the national emergency was declared that granted access to $1.375 billion to fund the border wall, much less than he sought.
She says if there was a true emergency at the border, Congress would provide funding. Whatevs. When will Congress get to other 31 and genuinely protect their constitutional prerogatives?
"The president's power grab usurps that responsibility and fundamentally violates the balance of power envisioned by our founders", said Pelosi, who has noted that the measure already has 226 supporters in the 435-member body.
