Late Tuesday, the president tweeted his condolences to the victims - except he referred to the deadly incident that occurred at the First Baptist Church in Sutherland Springs, Texas, on November 5, with no mention of California. "The FBI and Law Enforcement has arrived".
If this is not a sign of how much work needs to be done in this country, especially around mass shootings, I don't know what is.
Trump's tweet on Tuesday night should sound familiar. However, people on social media accused Trump of copying and pasting his heartfelt condolences, given the similarity between the tweet on November 5 and the one sent out on Tuesday night.
A gunman randomly killed four people and wounded a number of others at multiple locations in rural Northern California, including an elementary school, before police shot him dead on Tuesday.
On Nov. 5, Trump tweeted almost the same thing about the shooting in Texas, where a gunman killed 26 people at a church.

It is not the first time that the Russian defence ministry has tried to pass off footage of other events as its own. Russia said the Americans actively interfered with Russian airstrikes, to provide cover for the Isis fighters.
As of Wednesday morning, Trump's tweet was still up, and the president had not posted any statements or corrections about it.
The tweet remained on the President's Twitter page for five hours, but has now been deleted.
Another Twitter user wrote: 'He's mixed up mass shootings, confusing the one last week in Texas with the one in California today.
Bottom line: Offering thoughts and prayers after yet another mass shooting is the very least one can do in such a situation, but even with such a low bar, President Trump manages to fail.
