A judge overseeing the upcoming second trial of former Trump campaign manager Paul Manafort on Tuesday approved the prosecution's request to allow evidence about a Justice Department inspection of Manafort's lobbying activities in the 1980s but limited the scope of what it can show.

The ruling by Judge Amy Berman Jackson represents a partial win for special counsel Robert Mueller ahead of Manafort's second trial, which is set to begin next month in Jackson's federal courtroom in Washington.

Jackson said she wanted to limit the scope of what the government introduces in order to avoid a "trial within a trial" that would involve reviewing reams of evidence.
