WASHINGTON • Put Sen. Roy Blunt, R-Mo., down as supportive of House Speaker John Boehner's plan to sue President Obama over a president's constitutional duties to make sure that laws are "faithfully executed."

Obama, in the wake of a Congress that has been gridlocked on virtually everything, has issued controversial executive orders on issues ranging from gay rights to the environment. It is part of a "pen and phone" doctrine Obama had promised to adopt, as the Republican House and the Democratic Senate have failed to come to agreements on immigration, energy, and other pressing issues. Obama also has announced he would not enforce certain laws he deems unconstitutional, such as the Defense of Marriage Act.

Blunt introduced legislation with a catchy acronym - Executive Needs to Faithfully Observe and Respect Congressional Enactments of the Law (ENFORCE the Law) - that has virtually no chance of passing a Senate run by Democrat Majority Leader Harry Reid.

But the bill did give Blunt a platform Thursday to say he supported Boehner. "The president's 'pen and phone' do not supersede the U.S. Constitution," Blunt said in an e-mail.
