President Donald Trump's oldest son said Tuesday he did not tell his father about meeting a Russian lawyer during the 2016 campaign, after the talk failed to yield compromising information about election rival Hillary Clinton.

"No. It was just a nothing. There was nothing to tell," Donald Trump Jr told the Fox network's "Hannity" show.

Hours earlier, he released a series of emails detailing an agreement to meet the Russian intermediary, who had promised to dish dirt on Clinton from Moscow. "It was literally just a wasted 20 minutes, which was a shame," he added.
