President Donald Trump said Sunday that “I’m not joking” about trying to serve a third term, the clearest indication he is considering ways to breach a constitutional barrier against continuing to lead the country after his second term ends at the beginning of 2029.

President Trump did not rule out seeking a third term in office on Sunday, telling NBC News that he was “not joking” about the possibility and suggesting there were “methods” to circumvent the two-term limit laid out in the Constitution.
