Trump Uses Florida School Massacre As Excuse To Attack FBI’s Russia Probe

President Donald Trump has criticized the FBI for missing “all of the many signals” about the suspected gunman behind Wednesday’s deadly high school shooting in Parkland, Florida.

In a tweet late Saturday, Trump said the agency’s failure was “very sad” and “not acceptable.” He also suggested the agency was “spending too much time trying to prove Russian collusion with the Trump campaign.”

“There is no collusion,” Trump claimed. “Get back to the basics and make us all proud!” he added.

The FBI acknowledged Friday that it had failed to act on a tip about 19-year-old Nikolas Cruz, who has since been charged with 17 counts of premeditated murder following the mass shooting at Marjory Stoneman Douglas High School.

Trump’s post followed Friday’s indictment of 13 Russians and three Russian entities by a federal grand jury empaneled by special counsel Robert Mueller. The Russians are accused of meddling with the 2016 presidential election and looking to boost Trump’s campaign.

In a series of tweets on Sunday morning, Trump sought to shift blame regarding Russia’s meddling in the 2016 presidential election on Democrats.
