U.S. President Donald Trump will sign an executive order on Tuesday that will seek to improve how police officers treat African-Americans and others by improving credentialing, training and mental health resources, administration officials said.

The order comes after Trump struck a strict "law and order" tone in his response to protests around the country sparked by the death of African-American George Floyd while in police custody in Minneapolis.

Trump has faced criticism from Democrats for his response and some allies are concerned that his handling of the protests and the coronavirus pandemic are hurting his and other Republican leaders' chances of re-election in November.

Senior administration officials said the order will aim to incentivize police departments to improve by tying federal approval of discretionary grants to good policing practices.

The order would encourage police departments to employ the latest standards for use of force; improve information sharing so that officers with shoddy records are not hired without their backgrounds being known and add social workers to law enforcement responses to non-violent cases involving drug addiction and homelessness, officials said.
