WATCH: White House pushes plan for $1 trillion infrastructure overhaul

The White House continued to push the Trump administration’s $1 trillion plan to modernize the country’s infrastructure on Monday, part of a weeklong rollout of one of the president’s signature campaign promises.

“The American people elected a builder to be the 45th president of the United States,” White House deputy press secretary Sarah Huckabee Sanders said in a news briefing Monday.

President Donald Trump’s plan to overhaul the nation’s crumbling roads, bridges, waterways and electrical systems began Monday, when he announced he would privatize air traffic control operations, a move celebrated by the U.S. airline industry.

Sanders called it a “great new era in American aviation, starting with modernization of our outdated air traffic control system,” referring to Trump’s plan to separate air traffic control operations from the Federal Aviation Administration.

The president argued that removing air traffic control operations from the guise of the Federal Aviation Administration would help with safety standards.

Sanders also announced that the President will not assert executive privilege to block former FBI Director James Comey from testifying as part of the Senate’s ongoing Russia investigation June 8 on Capitol Hill. While the “president’s power to exert executive privilege is very well established,” Trump will allow Comey to testify, “in order to facilitate a swift and thorough examination of the facts,” Sanders said.
