Vocativ described charges against its journalist Evan Engel as "unfounded and outrageous"
Two reporters in the US face charges after they were arrested while covering protests in Washington DC on Friday.
Anti-capitalist protests during Donald Trump's inauguration day saw protesters clashing with police and property damaged.
Police in the US capital say more than 200 demonstrators were arrested on Friday.
Court records show that Alexander Rubinstein of RT America faces felony charges under Columbia's Riot Act.
According to the Russian news agency, Mr Rubinstein was arrested "even though he showed police his media credentials" while covering the protests.
He was released on Saturday, and is due to appear in court next month.
Trying to get a video statement out about my arrest but it is not uploading yet. Stay tuned and follow @RT_America— Alexander Rubinstein (@AlexR_DC) January 20, 2017
Evan Engel, a reporter with Vocativ, faces similar charges, with a preliminary hearing scheduled for next month.
On Twitter, Mr Engel indicated that he and his publication "are fighting these charges".
Vocativ and I are fighting these charges and I’ll have more to share as soon as the legal process has run its course. Thanks all!— Evan Engel (@evanengel) January 24, 2017
In a statement reported by The Guardian, Vocativ indicated they "will vigorously contest this unfounded and outrageous charge".
According to The Guardian, the two men could face up to 10 years in prison and a fine of up to $25,000 if convicted.
