WASHINGTON - President Donald Trump has signed an executive order to help protect the United States from foreign interference in domestic elections by laying out a process for putting sanctions on countries and other actors who seek to meddle.

The Departments of State and Treasury would decide on appropriate sanctions to recommend and impose, US national security adviser John Bolton told reporters on a conference call.

Sanctions would include freezing assets, limiting access to U.S. financial institutions, and prohibiting US citizens from investing in companies involved.
