Obama: Americans must not let racist views become normalized

Former President Barack Obama, pictured at a conference in Berlin in April, tweeted Monday that Americans should reject language of "fear and hatred" from USA leaders.

The CBS Late Show host read a Monday tweet from President Barack Obama urging Americans to reject language from political leaders that "feeds a climate of fear and hatred or normalizes racist sentiments".

President Donald Trump will travel Wednesday to the scenes of back-to-back mass shootings that stunned the nation and left at least 31 people dead, but his planned appearances in OH and Texas aren't being well received by all local officials - some of whom say it would be best if the commander in chief avoided their grief-stricken cities. Trump has previously tempered his criticism of white supremacy, though he said in scripted remarks to the nation earlier Monday that the nation "must condemn racism, bigotry and white supremacy".

Obama denounced language from "leaders who demonize those who don't look like us, or suggest that other people, including immigrants, threaten our way of life, or refer to other people as sub-human, or imply that America belongs to just one certain type of people".

White House Deputy Press Secretary Hogan Gidley Tuesday rejected arguments that President Donald Trump's rally rhetoric played a role in the El Paso shootings Saturday, insisting that nobody is blaming Democrats for other shooting incidents.

He added that Obama's comments about not listening to leaders who use racist speech "take us backward and take us to a dark place that we never want to be and we never want to visit".

Trump also called for a bipartisan response to gun violence but stopped short of providing specifics on what he would support in legislation. But he said he supports "red flag" laws that would restrict access to firearms for "those who pose grave risk".

Calling for tighter gun controls, Obama said, "We are not helpless here".
