President Donald Trump's approval rating among Latinos shot up nearly 20 points from December to January in a new poll.

Key results in the latest NPR/PBS NewsHour/Marist Poll:

50 percent of Latinos support the job Trump is doing, a significant jump from the 31 percent who had the same answer in a December poll.

Trump's support among whites dropped from 50 percent to 40 percent, while his support among African-Americans fell from 19 percent to 11 percent.

Overall, Trump's approval in the most recent poll is 39 percent, down from 42 percent in the previous poll.

The ongoing government shutdown began Dec. 22 after lawmakers could not agree on funding Trump's border wall between the United States and Mexico.

Trump earned the support of 28 percent of Hispanics in the 2016 election, far below Democrat Hillary Clinton's capture of 66 percent.
