Venugopal, who was in Kerala, told over phone: "Yes, I am aware that Rahul Gandhi has resigned... a decision on electing a new party chief will be a collective one."
Asked when a meeting of the Congress Working Committee - the party's highest decision-making body, will be called to decide on the new chief, he refused to answer.
His remarks came after Gandhi announced that he has resigned as the Congress President, taking blame for the party's rout in the Lok Sabha elections where it could win only 52 of the 542 seats.
In an open letter posted on his Twitter account which no longer described him as the Congress President, Gandhi, son of UPA Chairperson Sonia Gandhi, also said that the BJP's sweeping election win proved that the RSS aim of capturing the country's institutional structure was now complete.
"As President of the Congress party, I am responsible for the loss of the 2019 election. Accountability is critical for the future growth of our party.
"It is for this reason that I have resigned as Congress President."
Two days after the election results were announced on May 23, Gandhi announced that he would resign as the Congress chief. He was himself defeated in family pocket borough, Amethi in Uttar Pradesh, but won from Wayanad in Kerala.
