U.S. President Donald Trump is in London this week to attend the NATO summit as his impeachment fight back home enters a new phase. "It will never end, because they want to do what they want to do," Trump said to reporters as he left the White House, referring to Democrats' impeachment inquiry.

With Democrats beginning hearings on drafting the articles of impeachment Wednesday, many leaders of the North Atlantic Treaty Organization are well aware of the pressures Trump is facing at home.

Impeachment hearings "eat up a considerable amount of time" for the president and his closest advisers, said Gary Schmitt, resident scholar in strategic studies and American institutions at the American Enterprise Institute. "You'll see a very distracted president for sure," Schmitt said.



However, Trump's impeachment will not likely impact discussions among NATO member countries whose leaders "probably anticipate that the president will be impeached but won't be removed from office," said Schmitt.

"They know that at least for the next year they'll be dealing with President Trump and his administration so they'll plan accordingly," he said.

This is not the first time Trump will be facing world leaders under the threat of impeachment. Speaker Nancy Pelosi announced the formal House impeachment inquiry against the president on Sept. 24, the same day Trump gave a speech in front of the 74th session of the United Nations General Assembly in New York.
