( CNN ) -- The Venezuelan government initiated a new charge against a private television broadcaster and said that 29 additional radio stations would soon be closed , the latest move in what critics call a crackdown on freedom of expression . Demonstrators hold up a picture of Venezuelan President Hugo Chavez at a pro-Chavez rally on Saturday . The Saturday announcement by Minister of Public Works and Housing Diosdado Cabello , who oversees the state telecommunications regulator , came at a counter-rally to marches protesting the hardline tactics of President Hugo Chavez . Friday 's marches against Chavez were in part to protest the government 's closure of 32 radio stations and two television broadcasters last month . The government said the stations were shut down for violations relating to their broadcast licenses . Critics say the president was clamping down on critical press . `` There are 29 [ radio stations ] that will be off the air shortly , '' Cabello said at Saturday 's pro-Chavez rally . Cabello also announced a new legal complaint against television broadcaster Globovision as a sanction for allegedly calling for a coup against Chavez during its coverage of Friday 's rallies . Globovision carried text messages from viewers on a ticker on the bottom of the screen during the anti-Chavez protests that called for an overthrow of the government , Cabello said . `` If you call for a coup , if you call for assassination , assume your responsibility , '' he said . The government has already initiated a number of charges against Globovision . The station , known for being critical of Chavez , is being investigated for breaking a law on `` social responsibility '' on some programs on certain dates . The station violated a statute that makes it illegal to utilize telecommunication channels to further criminal acts , the government alleges . Venezuelan authorities had also opened an investigation into whether Globovision broke the law May 4 when it reported about an earthquake before an official report had been issued on the matter . Two other investigations had previously been launched against the station . The relationship between privately-owned media in Venezuela and the leftist Chavez have never been rosy . Chavez has accused private television stations of supporting his brief ouster in 2002 , and the president was a driving force behind denying a license renewal in 2007 to one broadcaster he said cooperated with the opposition .
Venezuela says 29 more radio stations to be closed ; 32 already shut down . Minister also announces new charges against TV station critical of president . Critics say President Hugo Chavez ' government is trying to silence press criticism . Announcements come at pro-Chavez rally , countering anti-Chavez rallies on Friday .
