SAN ANTONIO (KTSA News) — One of the people looking to unseat President Trump in the 2020 election says he believes the President’s most recent Twitter activity is a campaign strategy.

On Sunday, former San Antonio Mayor Julian Castro appeared on CBS’ Face The Nation. He says he believes Trump’s attacks on House Oversight Committee Chairman Elijah Cummings is part of a broader “racial priming.”

“There’s a pattern here. This guy is the biggest identity politician that we have seen in the last 50 years and he engages in what’s known as racial priming.”

Castro says it’s part of Trump’s strategy to get re-election support.

“Using this language and taking actions to try and get people to move into their camps. That’s how he won in 2016 and that’s how he thinks he’s going to win in 2020.”

When asked about President Trump’s latest comments on House Oversight Committee Chairman Elijah Cummings, Castro says it’s important to call it out for what it is, which is racism.

The President had sent out a Tweet earlier in the weekend calling Cumming’s district a “rodent infested mess” where no human being would want to live.

President Trump also accused Democrats of trying to “play the race card.”
