President Donald Trump on Wednesday said his administration had not dropped its efforts to add a contentious citizenship question to the 2020 U.S. census, contradicting statements made by his own officials, including Commerce Secretary Wilbur Ross.

The U.S. Supreme Court on June 27 blocked Trump's plan to add the citizenship question, saying administration officials had given a "contrived" rationale.

Administration officials including Ross said on Tuesday that the census forms were being printed without the citizenship question.
