President Ellen Johnson Sirleaf's son, who just suffered a defeat in Liberia's Senate elections, is not ruling out a run for his mother's job.

Robert Sirleaf lost a December election to George Weah, a former soccer star and current opposition leader. He was once a presidential adviser to his mother and chairman of the board of the national oil company. He is now focusing on the professional soccer team he founded.

During an impromptu interview with The Associated Press at the home field of his Barrack Young Controller team, Robert Sirleaf wouldn't be pinned down about his plans, saying they depended on the will of the Liberian people.

His mother's term ends in 2017.

Liberia has been devastated by an Ebola outbreak that killed thousands; it currently has no patients.
