Sen. John McCain, R-Ariz., not only supports blocking President Obama’s executive actions on immigration but thinks Republicans could take him all the way to the Supreme Court, he said today in an exclusive interview with The Daily Signal.

McCain, interviewed at The Heritage Foundation after speaking about the Jones Act, suggested a “rifle shot” approach using government spending bills to “inhibit” Obama’s move to grant legal status to millions of illegal immigrants.

The Arizona Republican has been a key Senate proponent of amnesty for illegal immigrants as part of a comprehensive approach to immigration reform, but opposes unilateral action by the president that goes around Congress.

He is comfortable with the House’s “piece by piece” approach, McCain told The Daily Signal, and thinks border security should be the “first objective.”

House Republican leaders propose funding the government through next September, the end of the fiscal year, but providing money for the Department of Homeland Security, which enforces immigration laws, only until early next year. If Congress doesn’t pass a spending bill by Dec. 11, it could mean another partial shutdown of government.
