trump and so-called maga republicans, and he said trump and his forces were determined to take the country backwards. in a rare primetime address, president biden attacked fme president trump by name, calling trump and some of his supporters threats to democracy. >> donald trump and the maga republicans represent an extremism. not every republican, not even the majority of republicans are maga republicans. maga republicans do not respect the constitution. they do not believe in the rule of law. >> reporter: president biden condemned the january 6th attack on the capitol while urging americans to vote in midterm elections less than ten weeks away. >> we can't pro-insurrectionist and pro-american. they're incompatible. we can't allow violence to be normalized in this country. it's wrong. >> reporter: biden's remarks come days after he accused republicans by embracing semi-fascism by following trump. kevin mccarthy said he should have apologized for that

comment. >> they're in charge of every federal agency responsible for our law enforcement, for drug enforcement, for our homeland security, for our border security. are you better off? >> reporter: meanwhile, abc news has learned newt gingrich received a letter from the january 6th committee requesting the former speaker of the house testify about his contacts with the white house, specifically tv ads he helped trump's team produce after the 2020 election. the committee writing, these advertising efforts were not designed to encourage voting for a particular candidate. instead, these efforts attempted to cast doubt on the outcome of the election after voting had already taken place. and in a separate investigation into january 6th, former trump white house counsel pat cipollone and former deputy whit house counel pat philbin are expected to appear before a federal grand jury today. it all comes as a judge issues the longest sentence yet, thomas

webster, a former marine and new york city police officer was given ten years in prison for assaulting a police officer during the riot. hours before webster's sentencing, trump said, if he was ever elected president again, he would look into issuing full pardons to people charged in the attack. >> i will look, very, very favorably about, about full pardons. it's a disgrace what they've done to them, and i mean full pardons with an apology to many an apology. >> amen. >> they have been so badly, so badly treated. >> trump also said he was offering some financial support to some of the people involved in the attack. former president trump and the justice department are waiting to hear from a federal judge over an intense hearing over the classified documents the fbi retrieved from mar-a-lago. trump wants an outside expert to review the records, which his lawyers likened to an overdue library book. abc's justin finch joins us live from washington with the latest on this. good morning, justin. >> reporter: rhiannon, good morning. former president trump is calling for the court to appoint

a so-called special master to go through hundreds of documents seized from his florida estate. the expected ruling comes after weeks of back and forth. this morning, a federal judge could hand down a crucial decision in the fight over documents related to the fbi search of former president trump's mar-a-lago residence. the judge is contemplating whether to appoint a special master, an independent legal expert to review the classified materials agents found during the search. >> are you confident the judge is going to rule in your favor? >> reporter: lawyers for trump and the justice department faced off in the florida courtroom yesterday laying out arguments for how the documents should be handled. trump's lawyers downplayed the criminal investigation comparing the documents to an overdue library book. the justice department said, trump lost access to the hundreds of classified documents when he left office adding, government records were likely concealed by the trump team, and efforts were likely taken to

obstruct the investigation. the judge indicating she is in favor of appointing a special master. >> she had tough questions for each side and asked the trump attorneys why it took two weeks to make the request and she asked doj attorneys, wasn't there a way to put a special master in place without stopping the ongoing assessment. >> reporter: trump repeated claims he was not to blame for any top secret documents leaving the white house. >> you accumulate a lot of stuff over a term, and then all of a sudden you're leaving, and stuff gets packed up and sent. all sorts of stuff. you know, mostly the boxes, pictures and newspapers and shirts and gear and, you know, golf balls and just it's a lot of stuff. >> reporter: but the discovery of classified material at mar-a-lago is drawing criticism from some republicans. >> they should never be taken from the white house in the first place, but we just don't know the details yet. >> reporter: now, if the judge rules in favor for trump, lawyers for both sides will

offer suggestions for who will review those materials, but that decision will ultimately be made by the judge. rhiannon. >> justin finch in washington, thank you. the cdc has approved updated covid boosters. that means shots could be available as soon as this weekend. the newly designed vaccines take aim at the most common omicron strains, which now cause nearly all covid infections. the government has bought 170 million doses, which will be available for free to anyone 12 and older. now to the williams sisters overpowered in their doubles match at the u.s. open in what's expected to be the last time venus and serena ever play together professionally. and later today it could be the final time we see serena in action. abc's andrea fujii explains. >> reporter: this morning, a heartbreaking loss in the u.s. open's doubles first round for sisters venus and serena williams in what could be the last time they play together in a pro tournament. after about a two-hour match in

arthur ashe stadium, the williams sisters fell in straight sets against a team from the czech republic. they played a packed house, and despite the crowd going wild, they could not pull ahead. >> a sad ending, but it's got to end at some point, and i think we figured it wouldn't end in the finals. >> reporter: the sisters have had remarkable careers as partners winning 14 women's doubles grand slams. but the last time they played together was at the 2018 french open and reached the round of 16. >> they were at the time the best doubles team in the world even if they weren't playing as much. they definitely gave it up for the most part about halfway through their career. >> reporter: this was venus' last match of the u.s. open after her first round singles loss tuesday. but serena continues her farewell tour today with the match against australia's ajla tomljanovic. despite entering the tournament ranked 605th, on wednesday, serena beat the second ranked player in the world, some
