Tim Walz will speak at Democratic convention in opportunity to address wider audience

The joyful warrior' will seek to build on the momentum of his and Kamala Harris's campaign

Tim Walz will seek to build on the intense enthusiasm surrounding his and Kamala Harris's campaign on Wednesday, as the newly anointed vice-presidential nominee headlines the third night of the Democratic national convention in Chicago.

The speech will give Walz an opportunity to introduce himself to a much wider audience of voters, as most Americans were unfamiliar with the Minnesota governor before Harris selected him as her running mate earlier this month. An ABC News/Ipsos poll conducted last month, shortly after Joe Biden withdrew from the presidential race and endorsed Harris, showed that only 13% of Americans knew enough about Walz to register an opinion of him.
