Trump celebrated the news of Mueller's passing, writing on Truth Social: 'Good, I’m glad he’s dead. He can no longer hurt innocent people!' Trump has disliked Mueller since the latter was charge of the investigation into the Russian interference in the 2016 election, which the president won. Trump labeled the investigation a 'witch hunt' and frequently attacked Mueller. The former FBI director spent two years investigating, concluding that Russia had interfered with the election to benefit Trump.
