Rally targets congressman who wrote to activist's employer

MORRISTOWN, N.J. (AP) -- Dozens of people are protesting a GOP congressman who wrote a letter to a donor mentioning that a member of an opposition group worked for him.

NJ.com (http://bit.ly/2q4CmTY) reports the protesters gathered at Rep. Rodney Frelinghuysen's office in Morristown on Friday.

Frelinghuysen's letter to a board member of Lakeland Bank in March included a handwritten note saying one of the "ringleaders" of the liberal activist group NJ 11th For Change worked at the bank.

Bank attorney Saily Avelenda said this week that she resigned after being questioned about her involvement in the group.

Frelinghuysen's campaign downplayed the letter as "brief and innocuous."

The bank tweeted that its employees are allowed to "support the political process" as they choose.

A nonpartisan watchdog group has asked the Office of Congressional Ethics to investigate.
