The 44-year-old former mayor first announced his interest in running early this year. Just before the midterm elections last month, he said he was “likely” to challenge President Donald Trump in 2020.

\"I'm likely to do it. I have a strong vision for the country. I believe that our country's going in the wrong direction and that it needs new leadership. I'll make a final decision after November, but I'm inclined to do it,\" Castro told Rolling Stone in October.

He told the Associated Press this week that he knew which direction he was leaning, \"for sure,\" with regard to whether he's going to seek the Democratic nomination.

Castro would likely be the most prominent Latino running this election cycle, and he will likely face a crowded primary field if he goes in for the nomination. He has already made repeated visits to New Hampshire and Iowa — two early primary states that are seen as barometers for party nominees.

“If I decide to run, it would be because I believe I have a compelling message and I'm going to work hard and get to the voters and I believe I can be successful,” he told the Associated Press this week.
