WATCH: Biden touts his administration's infrastructure investments at White House event

President Joe Biden will deliver remarks at the White House promoting infrastructure investments on Tuesday.

Watch in the player above.

Biden’s remarks come as the presidential campaigns of Vice President Kamala Harris and former President Donald Trump ramp up ahead of the November election.

The Democratic vice president and the Republican former president will devote almost all of their remaining time and resources to just seven states. They will spend hundreds of millions of dollars targeting voters who, in many cases, have just begun to pay attention to the election. And their campaigns will try to focus their messages on three familiar issues — the economy, immigration and abortion — even in the midst of heated debates over character, culture and democracy.

The candidates will debate in one week in what will be their first meeting ever. The nation’s premier swing state, Pennsylvania, begins in-person absentee voting the week after. By the end of the month, early voting will be underway in at least four states with a dozen more to follow by mid-October.

In just 63 days, the final votes will be cast to decide which one of them will lead the world’s most powerful nation.

Privately, at least, both camps acknowledge that victory is no sure thing as they begin the nine-week sprint to Election Day. Harris and Trump are neck-and-neck in most national polls conducted since President Joe Biden ended his reelection campaign.
