Sen. Tom Cotton (R-AR) says it is “time for Democrats to end this nonsense,” referring to the now days-long federal government shutdown caused by Senate Democrats who demand an amnesty for millions of illegal aliens be slipped into a spending bill.

Cotton — President Trump’s closest populist ally in the U.S. Senate — is urging Democrats to put American citizens and their interests ahead of the interests of illegal aliens.

In a series of online posts, Cotton reiterated that Senate Democrats are unwilling to budge from their open borders viewpoints on immigration, demanding nothing less than amnesty for at least 3.5 million illegal aliens who are enrolled and eligible for the President Obama-created Deferred Action for Childhood Arrivals (DACA) program.

Last week, Senate Democrats, along with pro-amnesty Sens. Jeff Flake (R-AZ) and Lindsey Graham (R-SC), voted to shut down the federal government because the spending bill to keep the government running did not include the “Gang of Six” amnesty plan, which would give amnesty to millions of illegal aliens, as well as their parents who brought them to the U.S. illegally.

While millions would get amnesty under the Flake-Graham-Durbin plan, the legislation would also give a pathway to U.S. citizenship for 50,000 foreign nationals every year through two separate visa categories.

Despite their hard-line, open borders demands, Senate Democrats, Flake, and Graham knew the terms of an immigration deal with the White House, as the Trump administration has said for months that no deal would be made unless legal immigration levels were reduced to raise the wages of American workers and full funding for the border wall along the U.S.-Mexico border was handed over.

Senate Democrats, Flake, and Graham have been unwilling to stray from their “Gang of Six” amnesty plan and thus have attempted to blame Trump and senior adviser Stephen Miller for the shutdown, despite the terms of an immigration agreement remaining unchanged for months.

Cotton’s comments echoed Trump’s remarks on Monday, where he blasted Senate Democrats for shutting down the government unless they are given amnesty for illegal aliens.
