A bomb squad was called to the Arizona headquarters of Turning Point USA after a "suspicious bag" was left outside, the Daily Mail reports.
The Phoenix headquarters has drawn crowds of mourners since the horrific assassination of Turning Point founder Charlie Kirk on September 10.
The scene was declared safe after Phoenix police sent a bomb robot and bomb squad officer dressed in an Explosive Ordnance Disposal (EOD) suit.
"There is not a threat associated with this incident. Updates will be given out as they become available," police said.
Kirk was fatally shot in the neck during one of his trademark debates at Utah Valley University on September 10. The horrific assassination was captured on harrowing video witnessed by millions.
All across the world, the 31-year-old husband and father of two is being mourned as a martyr for free speech and civil debate. His callous murder has also been celebrated by a radical fringe on the left that has sought to disparage his legacy.
There have been numerous incidents of vandalism targeting memorials for Kirk around the country. A 19-year-0ld man was criminally charged for destroying a memorial at Turning Point's headquarters on Sunday.
The suspect wore the same shirt as the man accused of murdering Kirk, 22-year-old Utah native Tyler Robinson.
The left-alleged assassin, described as left-leaning by his family, confessed to killing Kirk because of the conservative activist's "hatred."
Robinson was charged Tuesday with aggravated murder, exposing him to being executed by firing squad - in addition to felony discharge of a firearm, two counts of obstruction of justice, two counts of witness tampering, and committing a violent offense in the presence of a child.
Kirk's political organization has been credited with fostering civil discourse and drawing young people to the right in the Trump era. His brutal murder has drawn attention to a rise in extremism and intolerance, particularly on the radical left.
President Trump has said he will designate anti-fa, a decentralized left-wing group, as a terrorist organization in the wake of Kirk's murder.
Kirk's funeral will be held Sunday at State Farm Stadium in Glendale, a 63,000-seat venue that is home to the Arizona Cardinals.
President Trump will make an appearance to pay respects to Kirk, who was a loyal supporter and friend of his.
Kirk, an evangelical Christian from the suburbs of Chicago, was raising a family in Arizona with his wife Erika, a Scottsdale native.
