Obama: My immigration plan will prevail in court

President Obama is confident his immigration actions will ultimately be upheld in court, but would still like to see Congress pass immigration legislation.

"I am confident that all the steps I've taken on my own to fix our broken immigration system will eventually be implemented," Obama said in an op-ed published in The Hill. "But I also continue to believe that these steps are no substitute for congressional action."

A federal judge ruled last week that Obama exceeded his legal authority with actions that would defer deportations for millions of migrants who are in the country illegally. Many analysts believe the issue is headed to the U.S. Supreme Court.

Lawyers are appealing that "misguided decision" in Texas, Obama said in his op-ed: "My administration will fight this ruling with every tool at our disposal, and I have full confidence that these actions will ultimately be upheld."

While defending his immigration actions, Obama also criticized congressional Republicans who would support a cut in the homeland security budget over the dispute.

Obama said his plans "will help us secure the border, prioritize scare resources, and hold millions of undocumented immigrants accountable by requiring them to pass background checks and pay taxes in order to have a chance to temporarily remain here without fear of deportation."

The president said he acted because Congress would not, but it is not too late.

Wrote Obama: "I welcome the opportunity to work with anyone who wants to build on the improvements we've put in place, and fix our broken immigration system once and for all."
