Less than an hour before President Trump was scheduled to deliver remarks on Wednesday’s shooting at a South Florida high school, his son Donald Trump Jr. showed support for a tweet blaming the FBI’s investigation into the Trump campaign’s ties to Russian election meddling for its failure to prevent the violence.

Special counsel Robert Mueller has investigated Trump Jr.’s Russian ties, including a June 2016 meeting at Trump Tower with a Russian lawyer. Emails setting up the meeting show the president’s son sought political opposition research on Democratic presidential candidate Hillary Clinton.
