House Speaker John Boehner issued a stern warning to President Obama ahead of Tuesday night’s State of the Union address: “We have a Constitution. We abide by it. If he tries to ignore it, he’s going to run into a brick wall.”

The House speaker was addressing concerns that Obama is preparing to bypass Congress this year with more executive actions. Advisers for days have signaled that Obama will promote that approach in his State of the Union address — and will use his “pen” and his “phone” in 2014 to achieve the results he wants.

The president took a first step in that direction on Tuesday, announcing an executive order raising the minimum wage for new federal contract workers to $10.10 an hour, from $7.25. Obama will use the move to apply additional pressure on Congress to approve a similar increase for all workers.
