"As parents we refuse sit by while the government removes children from their parents at the USA border", the organizers said when they announced the event.
Amid fierce political debate over a Trump administration policy that has separated immigrant children from their parents, Meghan McCain called out President Donald Trump's daughter and adviser, Ivanka Trump, for her silence on the issue.
The Trump administration separated more than 2,000 children from their parents since early May, garnering overwhelming backlash from the public.
Until Wednesday, the president, Homeland Security Secretary Kirstjen Nielsen and other officials had repeatedly argued the only way to end the practice was for Congress to pass new legislation, while Democrats said Trump could do it with his signature alone.
Particularly worrisome, Republican operatives say, is that the images and sound of children in detention facilities could have a lasting impact with suburban women and drown out the economic-success message the party has been pushing.
Just hours after doubling down on his administration's much-derided policy that triggers separations of migrant children from their parents, Trump braved frustrated and in some cases angry fellow Republicans to assure he wanted their swift resolution to the crisis.
Those arrested for crossing illegally are taken into U.S. Border Patrol custody and informed they will be charged with the crime.
But Senate Democratic leader Chuck Schumer of NY signalled that no such support would be coming, saying it's already in Trump's power to keep the families together.
Pictures and accounts of the separations sparked outrage and a rebellion among Republicans in Trump's own party, as well as global accusation that the USA was committing human rights violations.
"I don't think either of them can pass right now", Davidson said. "There will not be a grandfathering of existing cases", Health and Human Services Department spokesperson Kenneth Wolfe said. An earlier report from Fox News Channel said the Trump administration was considering an executive order that would allow immigrant families who cross the southern border illegally to stay together longer than is now permitted.
The Trump administration has defended the separations in several ways, claiming that it's necessary for national security.
Senate Majority Leader Mitch McConnell, R-Ky., told reporters that all Senate Republicans are supporting the plan.
The order also provides that the Department of Homeland Security won't detain an immigrant family together "when there is a concern that detention of an alien child with the child's alien parent would pose a risk to the child's welfare".
The last-minute decision came at almost the same moment the House killed another more conservative immigration bill - also supported by Trump and GOP leaders - by a vote of 193-to-231.
Protesters walk though the streets as they protest against the Trump administration's immigration policies on June 21, 2018 in El Paso, Texas.
Colorado Rep. Mike Coffman, one of the nation's most endangered Republicans in this year's midterms, said in a statement he told Sen.
Instead, the process requires coordination between Immigration and Customs Enforcement (ICE), which holds numerous parents, and HHS, which takes custody of children and places them with adult "sponsors".
Because the Justice Department can't prosecute children along with their parents, the result of the zero-tolerance policy has been a sharp rise in the number of children detained separately.
"We do not want children taken away from their parents", Ryan, R-Wis., said.
But even after the meeting, it was unclear which of two rival immigration bills being brought by Republicans Trump favors. Rep. Luis Gutierrez, D-Ill., said Americans were "standing up for children, standing up for those who are in need". Last fall, the president nixed an Obama-era program that provided legal status and work permits to the so-called "Dreamers", the undocumented immigrants who came to the U.S.as children.
The House is slated to vote on a pair of immigration bills on Thursday.
