The weekend shooting death of Rayshard Brooks by a white officer in Atlanta led to a renewed public outcry, more street protests and the police chief's resignation.
Trump regularly touts his support for police and is using the slogan "law and order" as a new pillar of his reelection campaign message.
The chamber's Republican majority is crafting its package of proposals, which includes a ban on chokeholds and increased used of police body cameras. They are not mutually exclusive.
Trump does not intend to acknowledge the role of systemic racism in policing, an official said, adding that the goal is "trying to bring people together with policy that will bring the country forward". "These standards will be as high and as strong as there is on Earth", said the president.
"A lot of the police departments that have had problems are not using the most modern standards", one official told reporters.
US President Donald Trump on Tuesday signed an executive order on police reforms that he said would deliver "elegant justice" as the nation is roiled by protests over the killing of black citizens by police.
"We have to find common ground, but I strongly oppose the radical and unsafe efforts to defend, dismantle and dissolve our police departments, especially now when we've achieved the lowest recorded crime rates in recent history".
Trump's executive order would establish a database that tracks police officers with excessive use-of-force complaints in their records.

This is good if you need an app to access the information for a task but don't want it idling away in the background tracking you. Till date, users only had the option to either give app permissions either all the time or deny it altogether.
Law enforcement officials and families of people who have been killed by police are expected to be part of the event where Trump will sign the order. Republicans are pushing to reduce job protections for members of law enforcement unions.
"While the president has finally acknowledged the need for policing reform, one modest executive order will not make up for his years of inflammatory rhetoric and policies created to roll back the progress made in previous years", said Schumer.
Inimai Chettiar of the Justice Action Network said the use of grant money to influence police department policies could be an effective way to get results, but she noted that Trump's Justice Department has resisted other reform efforts.
Democrats in the House of Representatives and Republicans in the Senate are preparing competing packages of policing changes as USA politicians seek to respond to mass demonstrations over the deaths of George Floyd and other Black Americans.
Kristina Roth at Amnesty International USA said the order "amounts to a Band-Aid for a bullet wound" at a time when "this moment is calling for transformational change of policing". "The chokeholds, that's common ground now between Pelosi and Trump".
Yet the Republican bill does not go as far as the Democrats do on the issue of eliminating qualified immunity, which would allow those injured by law enforcement personnel to sue for damages.
By contrast, Democrats and civil rights groups say that only full-scale rethinking of police culture, and sometimes a cut in police funding, will bring necessary change. As an alternative, Scott has suggested a "decertification" process for officers involved in misconduct.
