Political commentators have pointed to Graham's recent trip to Ukraine as a reason why the public remains skeptical of a natural cause of death.

"Putin has poisoned and assassinated many of his opponents, and Graham was just in Kyiv where there are certainly FSB agents operating," said Marc Thiessen.
To prevent further speculation, Thiessen urged authorities to conduct comprehensive medical testing.
"There should be a full autopsy and tox screen to rule out foul play," said Marc Thiessen.
In response to the growing public pressure, Graham's office confirmed that the final determination on the senator's death certificate remains on hold.
