Donald Trump has ramped up his criticism of the US judicial system as judges were examining the legality of his controversial ban on people travelling from seven mainly Muslim countries.<br /><br /> “I don’t ever want to call a court biased,” Trump told police chiefs and sheriffs in Washington, continuing, “so I won’t call it biased and we haven’t had a decision yet. But, courts seem to be so political and it would be so great for our justice system if they would be able to read a statement and do what is right.”<br /><br /> The president said he thought the country’s security was at risk.<br /><br /> The appeals court must decide whether Trump was within his authority to issue the executive order, or if it amounts to a discriminatory ban targeting Muslims. <br /><br /> It is not the first time Trump has called the US justice system into question. Last week he lashed out at the Seattle judge who put a temporary block on the ban, refering to James Robart as a ‘so-called judge’.<br />
