expression, godan verb (-ru)
to gloss over a mistake; to cover up an error with a veneer of correctness

彼は過ちを文るばかりで、根本的な解決をしようとしなかった。
He only glossed over his mistakes and never tried to address the root cause.

The politician didn't admit the gaffe and spent the whole time giving an explanation that merely papered over the error.
