How did senator j. william fulbright build support for the doves in congress?

The answer is:

- by holding hearings that provided a platform for war critics to build support against the war in Congress.

- Senator Fulbright challenged the testimony of administration officials in televised Senate hearings on Vietnam.

At that time, the media knowingly spread misleading information regarding the situation in Vietnam to maintain public support to the cause. The government feared that if they tell the truth, people would became panic knowing that we're losing on the foreign land.

J.William Fulbright became one of the central figures in advocating for the the order to take the troops back home and prevent united states from joining unecessary wars in the future.
