South African President Jacob Zuma has been admitted to the hospital for tests, his spokesman Mac Maharaj said in a statement Saturday.

“Yesterday President Zuma was advised to rest following a demanding election and transition programme to the new administration,” Maharaj said.

“Doctors are satisfied with his condition,” the statement read.

Zuma was re-elected to a second term last month despite economic woes, deadly mining protests and corruption allegations.

His party, the African National Congress, won the general election with 62% of the vote, which was lower than the previous election.

After a turbulent first term, Zuma said during his inaugural address that his government will perform better this time around and take responsibility for any shortcomings.

“We will … ensure much tighter accountability, with firm consequences where there is a failure to deliver services to our people,” he promised.
