First lady Melania Trump was sent into President Trump's meeting with Russian President Vladimir Putin to try to get the two leaders to wrap it up after their scheduled 30-minute meeting ran for more than an hour, Secretary of State Rex Tillerson said Friday.

She was unsuccessful; the meeting lasted more than an hour longer after U.S. officials sent her in, Tillerson said.

"Several times I had to remind the president, people were sticking their heads in the door," Tillerson told reporters after the meeting. "They even sent in the first lady at one point to see if she could get us out of there, and that didn't work either. … We went another hour after she came in to see us, so clearly she failed."

Trump and Putin met officially for the first time Friday on the sides of the G-20 summit in Hamburg, Germany.

The meeting lasted 2 hours and 16 minutes.

Earlier Friday, protests kept the first lady from leaving the residence where she and Trump are staying.
