U.S. Rep. Nancy Pelosi (D-CA) has joined those Democrats in the U.S. House Of Representatives who are calling upon President Joe Biden to call off an arms sale to Israel. 

CNN reports that Pelosi, last week, signed on to a letter that these House Democrats sent to Biden and Secretary of State Antony Blinken.

As will be demonstrated, though, not all Democrats agree that the arms sale ought to be called off.

"Concern and outrage"

The House Democrats who signed on to the letter particularly took issue with the recent Israel airstrike that reportedly killed several World Central Kitchen aid workers.

In case you missed it, NPR reported:

World Central Kitchen has named the seven aid workers killed by an Israeli airstrike Monday as they were trying to deliver food to Palestinians in Gaza. The victims were Australian, British, Palestinian, Polish and a dual citizen of the United States and Canada.

In the letter, Pelosi and the others argued that the arms sale ought to be called off because of this air strike.

"In light of this incident, we strongly urge you to reconsider your recent decision to authorize the transfer of a new arms package to Israel, and to withhold this and any future offensive arms transfers until a full investigation into the airstrike is completed," the letter reads.

The letter writers also told Biden that his efforts to increase humanitarian aid to Gaza are not enough.

A divided party

Not all congressional Democrats are on board with the contents of the letter.

In fact, many believe that the arms sales ought to continue. This includes U.S. Sen. Chris Coons (D-DE), a Democrat who is usually one of Biden's strongest congressional supporters.

During an appearance over the weekend on the Fox News Channel's Fox News Sunday, Coons said, "In the face of a possible attack from Iran, I don’t agree that we should in any way constrain or stop the delivery of defensive material that is essential for Israel’s defence."

Background

This all comes as Biden just recently spoke with Israel Prime Minister Benjamin Netanyahu. In recent weeks, the Biden administration has significantly softened its support of Israel in its war with Hamas, and this was evident in Biden and Netanyahu's conversation.

According to Blinken, during their talk:

The president emphasized the strikes on humanitarian workers and the overall humanitarian situation are unacceptable. He made clear the need for Israel to announce a series of specific, concrete, and measurable steps to address civilian harm, humanitarian suffering, and the safety of aid workers. He made clear that U.S. policy, with respect to GAZA, will be determined by our assessment of Israel's immediate actions on these steps

Biden, according to the secretary of state, also called for an "immediate cease-fire."
