Nearly 20 young children are captured in an online video song that overflow with campaign slogans and praise for "Barack Hussein Obama", as they repeatedly chant the US president's name and celebrate his accomplishments.

Everyone Loves Him: US President Barack Obama

The video shows the children dancing and singing a song about the president, quoting from his speeches and campaign slogans.

One verse says: 'He said that all must lend a hand. To make this country strong again.' Another goes: 'He said we must be clear today. Equal work means equal pay.'

As critics of the video claimed it amounted to "indoctrination", the tension at B Bernice Young Elementary School escalated to such a degree on Thursday that the school was placed temporarily on lockdown after its principal received death threats.
