President Obama and his team had illegal migration down to NET ZERO from 2012 on into 2017, and did that without this EMINENT DOMAIN REQUIRED wall that "Mexico is going to pay for," according to pathological liar Trump.
You are judging a woman as "evil" without any evidence to support your defamation. It was tiny Pisces with the heart of a LION Nancy Pelosi (D-CA) who, as House Speaker for the 111th Congress from 2009 through to 2011 was able to pass 362 pieces of quality legislation during her tenure---so effective a leader that C-SPAN News and the LA Times rated that 111th Congress as "the most effective Congress in more than 60 years, since Eisenhower."
President Obama was able to secure our borders without a show-off-for-cameras "wall" that would require government confiscation of private property of U.S. landowners through Eminent Domain as well as building in a river---adding how many TRILLIONS to the already exploded Trump deficit? When tough-as-nails former AZ Governor Janet Napolitano was appointed to head Homeland Security in the first months of 2009, she hit the ground running, changing the "random vehicle check" of the Bush administration to an immediate ALL VEHICLE inspection at border crossings for vehicles entering or leaving. These ALL VEHICLE inspections were for ALL possible contraband, not just one or two illegalities: money, weapons, humans, drugs---you name it and the every-vehicle inspections looked for it, prosecuting any wrongdoers. Next, Napolitano went after the tunnels, collapsing them once the equipment had been confiscated and examined. E-VERIFY was fully enforced, and any CEOs who knowingly hired undocumented workers were prosecuted. New border security agents were hired, and their technology was updated, plus new surveillance drones were used. When the Republican party, acting through the Jim DeMint-led COUP-seeking right-wing Heritage Foundation, using mercenaries-for-hire from right-wing Erik Prince's Prince Group, tried to pull of an election year dirty trick of dumping thousands of "unaccompanied minor aliens" (UMIs) at the southern border from the Central American countries a Bush-signed 2008 law prohibited from being automatically deported, thinking this dirty trick would undermine President Obama's border security credentials or his foreign policy bona fides, how did President Obama respond? The GOP-led House went on a second 15-week "vacation" to avoid making a simple change to allow deportation of the kids, but they also refused to fund the mandatory "due process" required for each illegal minor child, hoping to 'stick it to" the Democratic President in time for voting day. Didn't work, though. That day, President Obama joined with ICE and his 2012 Homeland Security director Jeh Johnson to set up OPERATION COYOTE, a covert operation to make MASS ARRESTS of human traffickers, capturing all these traffickers' equipment, including telltale cellphones, confiscating all their banked assets, and following the clues to capture the U.S. contacts---part of how the NET ZERO on illegal immigration occurred in 2012 and beyond.
No deficit-exploding idiotic wall was needed.
