President Donald Trump is planning to issue an executive order targeting a controversial Dodd-Frank rule that requires companies to disclose whether their products contain "conflict minerals" from a war-torn part of Africa, according to sources familiar with the administration's thinking.

Reuters could not learn the precise timing of when the order will be issued, or exactly what it will say.

However, the 2010 Dodd-Frank law explicitly gives the president authority to order the Securities and Exchange Commission to temporarily suspend or revise the rule for two years if it is in the national security interest of the United States.
