The US is prepping another $800 million military assistance package for Ukraine, according to three senior administration officials and two sources familiar with the planning.

Details of the latest package are still being privately discussed and could change, but earlier Tuesday, President Joe Biden said the US plans to send more artillery to Ukraine.

 Upon arrival in Portsmouth, New Hampshire, Biden was asked by reporters on the tarmac if he plans to send more artillery to Ukraine.

 Biden told reporters, "Yes," before boarding his motorcade.
