What the Evidence Shows
The question of whether Trump asked protestors to kill Mike Pence on January 6 is complex and has been widely investigated. None of the reliable sources provide direct evidence that Trump explicitly called for Pence's death. Instead, the evidence shows that during the Capitol riot, rioters chanted threats like 'hang Mike Pence,' and Trump was reported to have expressed support or sympathy for those chants. For example, POLITICO and The Guardian report that Trump defended or supported rioters who threatened Pence.theguardian.comtheguardian.comTrump defended rioters who threatened to ‘hang Mike Pence’, audio reveals

Additionally, FactCheck.org clarifies that what Trump asked of Pence was to 'simply pause' the certification process, not to harm him. There are also reports of tension between Trump and Pence, including threats in phone calls before January 6, but these do not amount to calls for violence.
