(CNN) -- President Barack Obama dared Republicans to follow through on their threats to bring a lawsuit against his administration over his use of executive action.
"Middle-class families can't wait for Republicans in Congress to do stuff. So sue me," Obama said Tuesday at an event in Washington.
"As long as they're doing nothing, I'm not going to apologize for trying to do something."
Obama's defiant attitude comes as House Speaker John Boehner, a Republican from Ohio, plans to propose legislation that could bring a lawsuit against him for implementing executive actions that the GOP contends amounts to a breach of his constitutional power by side-stepping the legislative process.
Recently, Obama has ramped up his use of executive authority as a way to bypass Congress, avoiding inaction on issues the White House has made hallmarks of the President's second term agenda.
On Monday, Obama said he would start "a new effort to fix as much of our immigration system as I can on my own, without Congress."
At Tuesday's event, Obama continued to harp on congressional Republicans to pass legislation - this time pushing them to invest in transportation.
Standing in front of Key Bridge, which connects the city's Georgetown-area to Virginia, Obama continued his stepped-up rhetoric hammering Republican for obstructing action in Washington.
Obama proposed a long-term highway construction bill earlier this year that he says would spur job growth.
"It's not crazy, it's not socialism," Obama said of his transportation proposal. "It's not the imperial presidency - no laws are broken. We're just building roads and bridges like we've been doing for the last, I don't know, 50, 100 years. But so far, House Republicans have refused to act on this idea."
