Williamsburg, Virginia (CNN) - Former 2012 GOP vice presidential candidate Rep. Paul Ryan plans to attend Monday's inauguration of President Barack Obama.
The lawmaker from Wisconsin told reporters at the House Republican retreat in Williamsburg that he would be at the Washington ceremony, saying "it's my obligation."
But Ryan ignored a question about his plans for 2016.
He is considered among the top tier of potential presidential candidates next cycle and has not ruled out a bid.
He stoked speculation about a future presidential bid when he spoke about the future of his party at a December conservative awards dinner sponsored by the Jack Kemp Foundation.
Ryan encouraged his party to find a "vision for bringing opportunity into every life - one that promotes strong families, secure livelihoods and an equal chance for every American to fulfill their highest aspirations for themselves and their children." That vision, he said, includes roles for government, private groups and free enterprise.
At the dinner, he congratulated Obama on his re-election and said he hopes the president would "offer fresh ideas and serious leadership" in his second term.
On the presidential campaign trail this year, Ryan described Obama in stark terms. At an October event in Pennsylvania he said, "This is the third president I have served with. It's the most partisan one I have ever known."
Ryan could find himself at the center of a major policy debate between Obama and congressional Republicans over the debt ceiling, sequester, and funding the federal government. He is the chairman of the House Budget Committee.
Obama will officially take the oath of office at noon on Sunday January 20, as required by the constitution, but because inaugural ceremonies have traditionally not been held on Sundays, the public ceremony will take place on Monday.
