A New York Times reporter said it was an "oversight" on his part after critics on social media noted that his story about corruption charges facing Sen. Bob Menendez neglected to mention the lawmaker's Democratic Party affiliation.

The story, headlined "Menendez Trial Set to Begin With Tensions High and Washington Watching," published Monday night and initially did not include that Menendez is a Democrat.

"The New York Times wrote a 1,288 word article that never once informs the reader that the Senator facing a bribery trial is a Democrat," one person on Twitter observed.

The story was written by Times political reporter Nick Corasaniti.

Rs in my feed complaining @NYTnickc piece abt Bob Menendez doesn't mention he's a Democrat. I'll admit: It's ... odd https://t.co/iWqoP2HQfi — Evan Smith (@evanasmith) September 5, 2017

Evan Smith, CEO of the Texas Tribune newspaper, called the omission "odd."

Coransaniti replied that it was simply "an oversight on my part after drafts."

The online story was later updated to identifiy Menendez as a Democrat in the fourth paragraph.

Menendez is facing several bribery and corruption charges.
