U.S. Rep. Stephen Lynch has been named chairman of the House's National Security Subcommittee.
Lynch said one of his top tasks will be to restart congressional oversight of President Trump's national defense strategy, which he described as "ill-defined and prone to sudden and erratic revision."
The Massachusetts Democrat said he also wants to look into the use of cyberespionage against the U.S. government and private sector and will step up oversight of pipeline safety and security following a number of recent gas explosions across the country.
The committee's oversight efforts include national security, homeland security, foreign operations — including the relationship of the United States with other countries — immigration, defense and veterans.
Lynch said he's traveled to Afghanistan and Iraq as often as any member of Congress.
