President Joe Biden's European tour continues with a stop in Brussels for the NATO summit.
The president will use his time to reaffirm the U.S.'s commitment to the 30-nation alliance.
He plans to highlight Article 5 of the NATO charter, which declares that any attack on one member is an attack on all and warrants a collective response.
Ultimately, President Biden aims to have NATO keep better tabs on China and Russia, whose economic and geopolitical positions could complicate the White House's foreign policy goals.
