Fox News -- bolstered by its coverage of President Trump’s June 20 campaign rally in Tulsa -- continued its domination of the weekly cable ratings charts, according to Nielsen.

Fox News averaged 3.7 million viewers in primetime for the week of June 15-July 21 for its 23rd consecutive win, said Nielsen. Fox News was helped by a network record 6.6 million viewer primetime average on Saturday for its coverage of the Tulsa political rally. 

MSNBC finished second with 2 million viewers followed by CNN’s 1.6 million watchers. HGTV took fourth place with 1.1 million viewers followed by TLC’s 1.1 million viewers. TBS (975,000 viewers), Hallmark Channel (866,000), History (840,000), Food Network (820,000), and USA Network (785,000) rounded out the top 10 most watched networks for the week.

On a 24-hour basis, Fox News topped the charts for the 24th consecutive week. Fox News, MSNBC and CNN were the only three networks to average more than 1 million viewers in total day for the week, said Nielsen. 

A pair of legislators have asked the Department of Homeland Security for info on how they are protecting Donald Trump and other candidates at campaign events given that there have been "more than a dozen incidents of violence, arrests, and forcible removals over the past year.

They did not specifically cite the violence at Trump rallies, but since that story has dominated the news cycle in the past week or so, they did not need to.

Rep. Bennie Thompson (D-Miss.), ranking member of the House Homeland Security Committee and Bonnie Watson Coleman (D-N.J.), ranking member of the Oversight Subcommittee, wrote Homeland Security Secretary Jeh Johnson to ask what the department has done to "maintain situational awareness and response capabilities" (translation: monitoring and potentially responding to) that violence, which has sometimes occurred "in proximity to" the candidates themselves.

Again, without citing the recent incidents at Trump rallies--the letter was dated March 11, before the Chicago Trump rally was cancelled for fear of violence--they said that campaign rallies have "become havens for charged rhetoric, which has incited violence, particularly at "certain events" where the potential for violent activity is heightened.

They want a bunch of questions answered, including how the department monitors such events, what it does with that information and who it shares the information with.
