Here’s the history, ripped from the Media Matters archives.
2005 — 2012: Pat Buchanan and the “Reconquista”
There is a long American tradition of right-wing bigots warning that immigrants would contaminate and ultimately destroy the country. But President George W. Bush’s ultimately unsuccessful effort to pass comprehensive immigration reform legislation during his second term brought the issue to the fore this century and exacerbated a schism between the right’s pro-business, pro-immigration reform wing and its nationalist, immigration-restrictionist wing.
Right-wing restrictionists used the increasing migrant encounters at the U.S.-Mexico border during that period, an overwhelming majority of which involved Mexican citizens, to claim that the United States was suffering an “invasion” by that country.
“This is an invasion, the greatest invasion in history,” Buchanan wrote in his 2006 book, State of Emergency: The Third World Invasion and Conquest of America. “We are witnessing how nations perish. We are entered upon the final act of our civilization. The last scene is the deconstruction of the nations. The penultimate scene, now well underway, is the invasion unresisted.”
Buchanan and his allies, like Michelle Malkin, argued that the migrant influx was part of the “Reconquista,” a purported plot by Mexico’s government and Hispanic politicians in the U.S. to reclaim the American Southwest. “Chicano chauvinists and Mexican agents have made clear their intent to take back through demography and culture what their ancestors lost through war,” Buchanan explained. He argued that the “invasion” would cause a “balkanization of America” in which the Southwest “de facto is going to secede from this country.”
The “Reconquista” theory fell out of fashion in subsequent years, as migrants with Mexican citizenship fell from 85% of all border apprehensions to 20%. But even without the involvement of a purportedly hostile foreign nation, “invasion” rhetoric recurred on the right’s fringes whenever the immigration issue returned to the fore — and ultimately spread into its mainstream.
2013 — 2016: Laura Ingraham’s “invasion” talk helps take down Cantor, Breitbart’s lifts up Trump
Immigration reform once more seemed within reach during President Barack Obama’s second term. The U.S. Senate passed a bipartisan bill in 2013 that would have increased border enforcement, expanded legal immigration, and provided a path to citizenship for unauthorized migrants. With Obama promising to sign the bill, the remaining holdup was the Republican-controlled House — and right-wing immigration restrictionists like Laura Ingraham, then a prominent radio host and Fox contributor, demanding that the GOP legislators oppose reform.
But the first months of 2014 saw a near-doubling of unaccompanied minors apprehended at the border over the previous year, which experts attributed to a rise in gang violence in Central America. Obama’s June declaration that the surge constituted an “urgent humanitarian situation” requiring the provision of food, housing, and medical treatment for the children triggered a firestorm on the right — complete with claims that the kids constituted an “invasion.”
“The Obama administration has basically put out the welcome mat at the border: ‘Come on in, we'll feed you, we'll house you, we’ll clothe you, we'll get you medical care,’” Ingraham said in a Fox & Friends appearance. “This is an ongoing invasion into our country, and it is horrifying for our sovereignty and our rule of law.”
Ingraham also blamed Republican Eric Cantor, then the House majority leader and a congressman from Virginia who supported citizenship for young people brought to the U.S. as children, if not necessarily broader immigration reform, for aiding what she described as “an invasion facilitated by our own government.” And she did more than complain about him — she endorsed and campaigned for Cantor’s primary opponent, Dave Brat.
Brat won that June 10 election in a victory widely credited to the anti-immigrant rabble-rousing of demagogues like Ingraham. Cantor’s defeat sent a seismic shock through the GOP, and by the end of the month, House Speaker John Boehner informed Obama that immigration reform would not receive a vote that year. The increasingly powerful right-wing media had exercised its veto over the Republican agenda.
Soon after, immigrant “invasion” rhetoric began gaining traction on right-wing Facebook pages, Media Matters found. Breitbart.com, the far-right website controlled at the time by Trumpist Steve Bannon, sought to capture that fringe-right grassroots energy — and snag market share from Fox — with virulent anti-immigration content. By 2015, the site “became the center of a distinct right-wing media ecosystem,” Harvard researchers reported in a post-mortem on election coverage that cycle.
The right-wing media’s incessant fearmongering over the border eliminated any space within the party for reformers. The ultimate beneficiary was Trump, who launched his presidential campaign claiming that Mexico was sending “rapists” to the U.S. and promised to build a wall and make that country pay for it as his supporters touted his ability to turn back the purported “invasion.”
2017 — 2020: The migrant caravan and the mainstreaming of “the great replacement”
Trump’s ascension to the presidency put his party in control of the White House, Senate, and House of Representatives and left him ultimately responsible for the border. But as the 2018 midterm elections approached, Trump adopted Fox’s preferred campaign strategy by focusing attention on a caravan of migrants 1,000 miles from the U.S. border with Mexico, an “invasion” he falsely blamed on Democrats.
