The strength of former president Donald Trump’s endorsement will be tested once again tonight in the runoff primary between a candidate he previously backed and an opponent who he now supports to run against them.
Senator Richard Shelby is retiring at the end of this year and has endorsed and put money behind his former chief of staff Katie Boyd Britt. Initially, Mr Trump endorsed Representative Mo Brooks, who spoke at the “Stop the Steal” rally before the January 6 insurrection at the Capitol and criticised Mr Shelby’s support of Ms Britt.
