About 20,000 Mexican union workers clogged rush hour traffic in the capital Tuesday demanding that the recently ousted miners' union boss be reinstated.
Union leaders threatened to call a general strike if the government did not retract its support for the newly installed General Secretary of the miners' union, Elias Morales.
The government had earlier removed Napoleon Gomez from the elected position. Gomez has been under investigation by the government for alleged corruption.
Tuesday's march comes days after the 250,000-member National Miners and Metal Workers Union shut down most mining and steel operations across the country in a two-day strike to support Gomez.Some information for this report was provided by AP and Reuters.
