From the Associated Press:

NEW YORK – After months of flirting with politics, Donald Trump said Monday he won’t run for president, choosing to stick with hosting “The Celebrity Apprentice” over a bid for the Republican nomination.

The reality TV star and real estate mogul made his announcement at a Manhattan hotel as NBC, which airs his show, rolled out its fall lineup.

“I will not be running for president as much as I’d like to,” Trump said.

Trump’s office released a formal statement just as he was taking the stage. In it, a confident Trump said he felt he could win the Republican primary and beat President Barack Obama in the general election but had come to realize a presidential campaign could not be run half-heartedly.

So maybe Seth Myers was right: Trump was running as a joke.
