President Trump on Thursday defended his son's campaign season meeting with a Russian lawyer whom he believed had political dirt on Hillary Clinton – calling it a normal practice in a U.S. presidential election.
"It's called opposition research," Trump said at a joint news conference with French President Emmanuel Macron. "Politics is not the nicest business in the world," he added.
Earlier this week, Trump Jr. revealed email correspondence showing he was told the potentially incriminating information about Clinton would be coming from the Russian government.
Saying "most people" would have taken the meeting, Trump also called Donald Trump Jr. "a wonderful young man" and "a fine person," and that in any event "nothing" came of the meeting.
Trump and Macron spoke to reporters after a series of meetings in Paris in which the leaders pledged cooperation on issues like counter-terrorism and maintaining a ceasefire in Syria, while continuing to disagree on what to do about climate change.
The younger Trump said this week that he thought the meeting was part of standard opposition research, and that he did not realize the potential ramifications of meeting with a foreign national on the subject.
Trump Jr. said the lawyer did not have information on Clinton, but only wanted to talk about U.S. sanctions on Russia.
Sen. Chuck Grassley, R-Iowa, chairman of the Senate Judiciary Committee, said Thursday he would send Trump Jr. a letter asking him to testify about the incident as soon as possible.
House Speaker Paul Ryan, R-Wisc., also said Thursday that anybody asked to testify before the Senate should do so.
