(CNN) Democratic presidential candidate Pete Buttigieg on Friday released a timeline of his three years working for the elite consulting firm McKinsey.

The release comes after some of Buttigieg's presidential opponents called for him to be more transparent about his time at the firm as some of McKinsey's work for the federal government, including for Immigration and Customs Enforcement on projects along the US-Mexico border, drew increased scrutiny this month.

Buttigieg detailed seven projects in the release.

"To the best of my recollection, these are all of my client engagements during my time with the firm, but a full release from McKinsey will allow the American public to see the full scope of my work," Buttigieg says in the statement.

The release does not include a detailed list of his clients, something that he has been called to release but rejected -- for now -- because of a nondisclosure agreement he has with his former employer. But Buttigieg, as part of the Friday release, gave the consulting firm "authorization ... to release the full list of clients I was assigned to serve."
