Petraeus is expected to tell congress he needs more time to implement the strategy that was aimed at bringing security to Iraq in order to push through political unity and reconciliation reforms.

The general and ambassador are also expected to acknowledge disappointing progress from the government of Nouri al-Maliki in Iraq in achieving political reconciliation.
For months, George Bush, the US president, has been asking the American public to wait for the White House report on Iraq, which has to be released by Saturday and will incorporate Petraeus's and Crocker's assessments, before they make up their minds, said Al Jazeera's Viviana Hurtado.
