Vice President Mike Pence is scheduled on Tuesday to headline a fundraiser for Rep. Chris Collins, R-N.Y., who is under investigation by the House Ethics Committee for possible insider trading in violation of federal law.

The luncheon event is raising cash for Collins Victory Fund, a joint fundraising committee comprised of the congressman’s re-election campaign and his political action committee. According to a copy of the invitation, donors are invited to contribute up to $20,000 to purchase an entire table of eight. Individuals that write checks for $10,000 or more are invited to join a special reception with Pence, and take a photograph with the vice president.
