Sen. Ted Cruz, R-Texas, suggested that Americans could die if Senate candidate Abdul El-Sayed is elected, suggesting that the Democrat could use U.S. intelligence to tip off terrorists.
"If Abdul El-Sayed becomes the senator from Michigan, there is absolutely nothing to stop Chuck Schumer from placing Abdul El-Sayed on the Senate Intelligence Committee. The Senate Intelligence Committee has access to our most closely-guarded secrets. And if I am correct that he is a passionate supporter of the Muslim Brotherhood, there is a very real risk that Americans will die as a result," Cruz warned.
"We have American service men and women in harm's way fighting Muslim Brotherhood terrorists right now. And we also have intelligence covert operatives heroically going undercover trying to anticipate and stop terror attacks before they happen, before they kill Americans. We have every reason to believe that Abdul El-Sayed, if he found out, 'OK, they're about to apprehend these terrorists,' that he would let those terrorists know," Cruz claimed.
The El-Sayed and Rogers campaigns did not immediately respond to Fox News Digital's comment requests on Thursday.
Speaking to Fox News chief political anchor Bret Baier last week, the Democratic candidate said that he has "never been" and "never will be a member of the Muslim Brotherhood."
"I am interested in serving the United States. I'm interested in swearing an oath to the Constitution that every senator has swore an oath to," El-Sayed said.
El-Sayed is facing President Donald Trump-backed former Rep. Mike Rogers in the Michigan U.S. Senate contest.
High-profile races that will determine which party controls the Senate for the next two years are extremely tight, according to a new CNN poll, as Maine and Kansas remain close and Democrats extended their leads in Texas and Michigan.
Democrats, who are widely projected to win a majority in the House of Representatives, need to flip four Senate seats from red to blue in order to gain a 51-seat majority, protecting their majority from the vice presidential tiebreaker.
Maine
In Maine, Sen. Susan Collins, R-Maine, is the only Republican incumbent running in a state that went for Kamala Harris in 2024.
Collins' Democratic challenger is Troy Jackson, the former president of the state Senate who jumped into the race as a replacement for the previous nominee, scandal-plagued Graham Platner.
The race has no clear frontrunner, according to the CNN poll, though Jackson holds a marginal lead.
Forty-nine percent of respondents told the outlet's pollsters they favored Jackson, compared to 45% for Collins. While Jackson is slightly ahead, at least 12.5% of voters say they could still change their minds.
Respondents tied Collins to her party less than any other Republican running for Senate in the nation, with 46% of respondents saying they believe she would choose her constituents over the Republican Party.
With Collins managing to distance herself from Trump, her race has largely become a referendum on her own career. Three-quarters of respondents from either party told CNN pollsters that their choice was motivated more by Collins than Jackson.
In Michigan, despite warnings from some mainstream Democrats and the state's Jewish community, Democratic candidate Abdul El-Sayed is building a lead over former Rep. Mike Rogers, R-Mich.
Respondents favored El-Sayed at 49% compared to the 42% who favored Rogers, according to the poll. CNN's previous poll, released in early September, showed El-Sayed with a 47% share compared to Rogers' 44%, showing the former public health director El-Sayed building on his lead.
The Democrat has consolidated his party's support after a contentious primary with Rep. Haley Stevens, D-Mich. Ninty-five percent of likely Democrat voters say they'll punch the ticket for El-Sayed, up from 90% in the September poll.
Rogers voters, meanwhile, are motivated more by dislike for the Democratic candidate than faith in the Republican. 57% told CNN pollsters they were voting against El-Sayed, up from 41% in a previous poll.
Rogers' favorability has also taken a hit, moving from 58% in September to 50% in October.
Texas
Texas State Rep. James Talarico also built upon a narrow lead over Republican Attorney General Ken Paxton, despite Talarico's extended absence from the campaign trail in early October.
Forty-nine percent of likely voters told pollsters they'd vote for Talarico, while 43% said they would vote for Paxton, according to the poll.
Texas, a state that has voted for exactly one new Democratic Senate candidate into office since Lyndon B. Johnson vacated his seat to become vice president, also voted more strongly for Trump in 2024 than in either of his previous elections.
Despite the typically steadfast support for the GOP in the Lone Star State, Talarico is riding a wave of favorability and minority support to remain in pole position five days before polls close.
CNN's poll says 64% of likely voters of color support Talarico, including 22% of the cohort that voted for Trump in 2024.
Talarico is also leading Paxton in favorability within their own parties. 24% of Republicans have an unfavorable view of Paxton, according to the poll. Just 2% of Democrats, meanwhile, view Talarico unfavorably.
Kansas
In Kansas, a state which Trump won by 16 percentage points in 2024, incumbent Sen. Roger Marshall, R-Kan., is falling behind Democratic challenger Adam Hamilton.
Forty-nine percent of likely voters say they support Hamilton, 45% say they support Marshall.
Hamilton, a relatively unknown candidate, is far outperforming his own party in a state where Democrats are broadly unfavorable. 57% of voters view the Democratic Party as unfavorable while only 38% of them feel the same about Hamilton.
Like Republicans in Michigan, likely voters in Kansas appear to be more highly motivated by a dislike for one candidate than strong positive feelings for another. 59% of Hamilton backers say they're motivated by opposition to Marshall.
Hamilton, a Christian pastor, is even drawing support from across the aisle. Roughly 12% of Republicans and Republican-leaning likely voters say they support Hamilton, according to the poll.
CNN conducted its polling via telephone between Oct. 20 and Oct. 27. Registered voters were randomly sampled, according to the outlet. 838 likely voters were considered in Kansas, 783 in Maine, 768 in Michigan and 923 in Texas. CNN tabulated its margins of sampling error at plus or minus 4.5% for Kansas and Maine, 4.7% in Michigan and 4.2% in Texas.
