Sen. Lindsey Graham, R-S.C., said Thursday that some "nut job" sent suspicious packages with potential bombs to high-profile Democrats, brushing off complaints that President Trump's pointed rhetoric is to blame.

“About the nut-job sending bombs in the mail –- Simply put, this is NOT the way we do business in America,” Graham tweeted. “I didn’t blame Bernie Sanders when a Bernie supporter shot Congressman Steve Scalise. And I’m not going to blame President Trump for this nut job.”

Since Monday, nearly a dozen suspicious packages including potentially explosive devices have been mailed to the homes and offices of prominent Democratic political figures, actors and media organizations -- all of whom have been critical of Trump at one point or another.

The FBI and Secret Service continue to investigate the incidents.

After yesterday’s flurry of bomb-related news, the president became the target of blame suggesting his rhetoric and constant outspoken animosity for Democrats and “fake news” media inspired the plot.

Graham, who in his tweet referenced the politically-motivated shooting of Rep. Steve Scalise during a congressional baseball practice last summer, is in most cases an ardent defender of Trump and his administration.
