Secret group of US defence officials warns 10 states that Trump could send troops and ICE to polling stations

The network of about 10 current and former Pentagon officials includes some who once worked against authoritarian regimes abroad. For months they have privately briefed governors, election chiefs and lawmakers from both parties. Their fears include attempts to overturn results through voter-fraud allegations. Several still hold federal jobs but insist they are acting outside their official roles before the November 3 midterms.

One member said state officials admit 'we don't know what to do'.

The White House dismissed the fears and warned illegal voters 'will be held accountable'.

Members admit their warnings rest on Trump's public remarks, not classified intelligence.
