I think you missed the back-handed-compliment that “it looks like it was written by the Clinton Library†means it looks like it was written by an source affiliated with Clinton.
Actually, this looks like it’s an insult to the Clinton Library. The Clinton Library wrote in a short one-page biography:
In 1998, his relationship with a young White House intern resulted in the President’s impeachment by the House of Representatives. A trial in the Senate found the President not guilty of the charges brought against him. President Clinton apologized for his conduct and vowed to keep working as hard as he could for the American people. As a result, Bill Clinton left office with historically high approval ratings for the job he had done as the 42nd President of the United States.

On January 21, 1998, a controversy was raised by the media and prominent Republicans[29] over Clinton's relationship with a young White House intern, Monica Lewinsky, resulting in the Lewinsky scandal. In a lame duck session after the 1998 elections, the Republican-controlled House voted to impeach Clinton for matters relating to the scandal. The Republican-controlled Senate then voted to acquit Clinton the following year, and he remained in office to complete his term.[30]
