(CNN) -- After months in detention, two Americans who had been held prisoner in North Korea soon will be back in the United States following a rare visit by a top U.S. official to the reclusive nation and a letter from President Barack Obama.

Kenneth Bae and Matthew Todd Miller, the last two Americans detained in North Korea, were due to arrive at Joint Base Lewis-McChord in Washington state about midnight ET (9 p.m. PT).

The pair were released after Director of National Intelligence James Clapper went to Pyongyang as an envoy of President Barack Obama, a senior State Department official told CNN.

Clapper delivered a letter from Obama, addressed to North Korean leader Kim Jong Un, describing Clapper as "his personal envoy" to bring the Americans home, a senior administration official told CNN on Saturday.
