The president's tweets came the morning after The Washington Post first reported that the administration had at one point considered sending immigrants in the US illegally to cities the administration has deemed "sanctuary cities".
The Post said the plan was rejected both times.
The president has been in a long-running battle with Congress over the crisis as the southern border.
"If the Radical Left Democrats all of a sudden don't want the Illegal Migrants in their Sanctuary Cities (no more open arms), why should others be expected to take them into their communities?", Trump wrote on Twitter.
US President Donald Trump once again called on Democrats to support tighter immigration laws, threatening to dump "an unlimited supply" of illegal immigrants in so-called sanctuary cities to force a change.
ICE Deputy Director Matt Albence denied that the White House pressured immigration officials to implement the idea.
But White House officials are emphasizing that the plan "never went anywhere".
Miller was angered that department lawyers refused to produce legal guidance that would make the plan viable, saying the proposal would likely be illegal.
"We're looking to see if there are options that make it possible and doing a full and thorough and extensive review", Sanders said. Another DHS official briefed on the matter disputed that the proposal reached Nielsen.
Pelosi's district lies entirely within San Francisco, a sanctuary city.
The transportation of immigrants who are arrested at the border to large and faraway cities would be burdensome and costly at a time when Immigration and Customs Enforcement is already stretched thin, having released more than 125,000 immigrants into the country pending their immigration court date since December 21.
America's Voice also argued that by having these cities in place, police have the ability to focus on more pressing, serious crimes instead of spending their time arresting and detaining undocumented immigrants.
The Transactional Records Access Clearinghouse at Syracuse announced this week that an analysis found that migrants in cities such as NY and Los Angeles are 20% less likely to be arrested than in cities without sanctuary policies. "Using human beings - including little children - as pawns in their warped game to perpetuate fear and demonize immigrants is despicable, and in some cases, criminal".
Ilhan Omar, a Democratic lawmaker from Minnesota, has been at the center of an escalating row following a speech she made about Islamophobia in which she was accused by conservatives of downplaying the deadliest attacks on U.S. soil by characterizing the event as "some people did something".
Speaking to CNN's "State of the Union", Scott said he did not know if transporting immigrants to these jurisdictions was legal or illegal, and he suggested the president could be bluffing: "I mean maybe he's just saying this to make everybody insane, make everybody talk about it on their shows".
