Parents and administrators at a UN school are looking for a diplomatic solution to the standoff over a controversial invitation for students to attend the stock exchange with Melania Trump.

A notice was finally sent to parents of students at the United Nations International School in New York asking the children to join the First Lady on a stock exchange tour and the opening bell tolls next week.

There is room for only 10 students on this tour, but that was enough to anger some parents who said they were worried that the children would be used for political propaganda.

“I was deeply disappointed with the school's decision to accept this invitation,” a UN staff member and a parent said in a letter to the Under-Secretary-General.

Others are concerned that "the emergence of children with the first lady, in and of itself, gives support to this American administration and the support of our school and our community," the father added.

In the letter received by the school and published in local media, the father also refers to special activities with students to counter the shock after President Donald Trump's election victory.

The guardian, who declined to be named, said the school should not accept the invitation.

The United Nations School in New York offers pre-K through 12 curricula and a college preparation program. The appearance of the first lady on the stock exchange on Monday coincides with the first day of the UN climate summit, where delegates from 63 countries are expected to speak.
