The White House is keeping its powder dry when it comes to increasing speculation that Vice President Joe Biden will run for president in 2016.

Asked whether President Obama has talked to Biden about the spike in speculation about such a run, White House press secretary Josh Earnest said Monday he anticipates that "the president will keep his private discussions with the vice president private."

"I don't have a lot to share," he said about Obama's feelings about Biden's potential bid to succeed him.

Earnest said Biden is expected to make a decision by the end of the summer and then touted the vice president's "extensive experience" and public service record.

"We're getting closer to the end of the summer, but we're not there yet," he said.

"Someone with the extensive experience of the vice president and someone who has made such a significant contribution" to the national security and prosperity of the United States, he said, "should be able to make that decision on a timetable that he chooses."
