Might want to park your ideology for just a millisecond and re-read the article, a tad slower:

"The current director of the budget office, Keith Hall, who signed the report issued Tuesday, was selected and appointed by Republican leaders of Congress in 2015."

Schumer (S-C-H-U-M-E-R) only requested the report. The report was signed by a Republican appointee. Whose goal in life is surely to make Democrats happy.
