President Trump calls for prayers ahead of his impeachment .

Donald Trump has called for prayers as he is expected to become only the third US president in history to be impeached later by the House of Representatives.
Democratic lawmakers are ready to approve two impeachment charges against the Republican president on Wednesday.

Mr Trump would then face a Senate trial next month, but members of his party control that chamber and it is unlikely to remove him from office. The president has called the process an “attempted coup” and a “scam”.
