US President-elect Donald Trump has nominated Exxon Mobil Chief Executive Officer Rex Tillerson to be secretary of state, an important opportunity to raise key human rights concerns, Human Rights Watch said today... As Exxon Mobil CEO, Tillerson oversaw lucrative business operations in partnership with abusive and corrupt oil-rich governments such as Equatorial Guinea and Angola. Under Tillerson, the company has been hostile to US laws requiring greater financial transparency in such countries and stronger human rights standards for companies – laws that the State Department has supported.
